Had one Barska scope, for long-range target shooting (Savage FLV 12 .223 and Rem 700 .243). Scope's innards fell apart such that it couldn't maintain zero, wasn't consistent on "click" adjustments, and it had always had marginal "foggy" visibility.
Am by no means a scope expert. Not in the least. I've only had a handful of them. The crappy Barska, a Vortex Crossfire, a couple of Nikon ProStaffs, a Leupold FX II "scout" scope. Other than the Vortex, each has been used at relatively short distances (<= 150yds).
If you're considering a relatively low-cost alternative, I'd recommend Vortex. Have had the Vortex Crossfire scope in 8-32x50 (~$200, though that particular model is no longer made); they're onto the Crossfire II series now. Have used this one at 600yds, though better optics, better light gathering and a finer reticle would be preferable (to me) that far out. Out to 300yds, though, nice. Very clear optics, accurate zero, accurate adjustments. At least, in the one scope of theirs that I have used. Great value for the money, I think.
But then, it depends on what "sniper scope" means to you in terms of magnification and features. A decent Nikon 3-9x40 is hard to beat for the money, IMO. Clear, easy to use, reliable. Greater magnification alternatives exist in the Nikon line, as well, if you need more power.
