A properly calibrated ballistic turret, coupled with a compact rangefinder, or a rangefinder binocular, that provides equivalent horizontal distance (i.e. adjusted for angle, and other environmental factors) works extremely well and provides the most flexibility.
Virtually every brand of riflescope allows for the installation of a ballistic turret these days, with some brands being better at it than others (i.e. Swarovski). Likewise the cost is becoming increasingly more reasonable: a Z3 4-12x50mm Ballistic Turret scope can be had for just over $1,000.
For compact rangefinders, there are a plethora of offerings, with the Leica CRF 1000-R ($649) and 1600-B ($849) being the clear winners in the under $1,000 bracket. The Bushnell Elite 1-Mile rangefinder also offers impressive features (1,700 yard range, archery/rifle modes, angle and ballistic compensation) at $599. The Zeiss rangefinder lacks modern features (no angle comp) and Swaro has retired the Laser Guide, presumably for an upgrade. For the long-range shooter, the G7 rangefinder ($1,899) is the obvious choice due to its range and the customizability of virtually all ballistic-related and environmental factors.
For civilian rangefinder binoculars (that provide equivalent horizontal distance), there are essentially four options: Bushnell Fusion 1-Mile, Leica Geovid HD-R, Leica Geovid HD-B, and Swarovski EL-Range.
Value-wise, the Bushnell Fusion 1-Mile wins by a landslide at $999: while the glass is okay, the rangefinder delivers straight-line distance out to 1,700 yards, angle compensation, and ballistic compensation (in the form of ballistic profiles), out to 999 yards. The Fusion's provide ballistic compensation in the form of inch hold-over, MoA, or Mils, so you don't even need a ballistic turret - just ping the target, the binos adjust for angle, and tell you how many inches to hold off, or how many MoA/Mils to crank on the turret. Essentially an "economy" version of the Leica HD-B's below.
Performance-wise, the Leica HD-B is the leader for civilian RF-binos: HD glass, 10 yard minimum range, 2,000 yard maximum, compensation for angle and ballistics out to 999 yards, compensation for environmental factors, as well the ability to input specific ballistic information (rather than ballistic profiles), by way of the G7 Ballistic Calculator, which can then be downloaded onto an SD micro card and input directly into the binos. However at $3,099 (or higher), they represent a sizeable investment. They are also the heaviest (90 grams heavier than the EL Range) and largest of the four mentioned.
The next best thing will be the soon to be released Leica Geovid HD-R. These are an upgraded version of the classic Leica Geovids HD's, now with the CRF 1000-R rangefinder: HD glass, 10 yard minimum range, 1,000 maximum range, and angle compensation starting from 10 yards, at around $2,499.
The Swarovski EL-Range, while still desirable, do not have the full functionality of the above mentioned BRF's: non-HD glass, 33 yard minimum range (frustrating to bow hunters), 1,500 yard maximum range, and angle compensation out to 999 yards (no ballistic or environmental compensation). And at a minimum advertised price of $3,479 in Canada, they are the most expensive of the lot.
Now for the Burris Eliminator III. I have been testing these for a few months now, and find them to be highly under-rated. Speaking frankly, the biggest hang-up/stigma with this scope is that it is put out by Burris. Cold performance is always an issue with electronics (do some Googling and you'll find posts lamenting EL Range letting some fellow down on a cold hunt, etc...), but I've stuck one of these in a -20 walk-in freezer for a day, and the RF worked fine. The Eliminator III relies on 123A batteries, which have reasonable cold weather performance, and are good enough for Surefire to use in military lights. As the scope stores your ballistic settings, simply pack around a few extra 123A's (they weigh nothing) in your warm, cozy pocket. I have a comprehensive review of this scope coming soon, however I've used this on a precision .308, and the RF and ballistic function worked well enough to place shots on a gong, out to 700 yards (maximum distance I could find to shoot). More testing is required, however I'm comfortable enough with the Eliminator III to consider using one on a two-week fly-in sheep hunt this coming year.
The Zeiss Diarange combines a rangefinder (999 maximum range) with a Victory riflescope. The RF does not compensate for angle/ballistics, however with a custom turret or Rapid-Z reticle it will get the job done. However at $4,000 USD...there are definitely other options to consider.
Of course, you could always just go all-in on a Tracking Point system =)
