I owned a few of the Tasco Varmint Mildot scopes. Great for the first few years, then it seemed that their internals started giving me grief (not so repeatable) so I gave them to friend with .22's needing glass. Great for horsing around the range, not so great at Mons Range where they served my son well for a couple of seasons shooting Precision and Service Rifle back in 2001.
If you really want inexpensive quality, the Bushnell 3200 Elite 10X Mildot is the best value IMHO. I quite liked the ONE set screw on the top that secures the tactical knob. Larger allen key needed... I liked that feature 3/32" I believe. The Tasco knobs could be reset after rezeroing, but the cheesy knobs would easily get stripped by the 1.5mm allen screws. This drove me crazy.
For a hundred bucks, give the Tasco Mildot varmint a try... You can always retire it to a .22 for kicks and giggles.
