I bought my Leica 800 on the EE used. IIRC the price was about that.
I doubt you would regret it, buying a used 'low end of the high end makers' unit.
Try to watch out for RF's that need strange, uncommon, or simply, expensive, batteries.
Dunno why they don't all run on a 9v square battery, but they deon't, so, be aware. PITA to find a oddball battery at a middle of nowhere dirt road gas station/hardware store/coffeshop/roadstop place.
If you can, get the rangefinders you think you can afford, out to the outdoors to try. A bud bought a Bushnell, and it felt like my eyes were being sucked out of my sockets when I went to pan across the area, you could actually see the world warp when it was moved. Ugh.
Try lots, save more money. If you choose well, you won't need to buy again for a long time.
