Your problem is that you are asking for way too much and you are gonna have to settle for now. Not being snobby just speaking from experience as I usually have to do the same. For starters, you are asking for way too much power in the lower priced scopes. I wouldn't go over 14-16x. I think your best bet is to find a mildot scope or the likes and learn to use the reticle. That way you don't have to worry about the turrets not tracking or returning to zero. Then about the only thing that can go wrong is it won't hold zero...which you should check often.
With that said, there are some decent scopes out there for a fella on a budget. The Nikon BuckMasters is one and so are most Weaver products. I bought a Nitrex TR2 2-10 to put on a sporterized 1903 Springfield to be my woods rifle. After checking the turret adjustments I was pretty impressed and put it on my heavy barreled 7 mag. For a little over $100 (after rebate) you aren't gonna beat the glass and turrets. It is the same thing as the Weaver Super Slam, and you get the same warranty. As impressed as I am with this thing it has not proven itself yet and I wouldn't trust it on a hunt of a lifetime. Maybe I should put it on my .338 and see if it'll hold up. They also have models with a drop compensating reticle if you don't trust the turrets.
