Glad you like the scope. Lots of guys complain about how horrible cheap scopes are, but I've had decent luck with them. Now not all of them have tracked the best and been repeatable, but once sighted in they all held zero and most of them had decent glass. Some of them track great, but a few others didn't move the 1/4" click like advertised, but still worked once sighted in.
That being said, I have one of the $30 Tasco scopes from Walmart on my muzzle loader and have been using it on a muzzle loader for 3 years now and it holds zero, and has always shot the same spot. The only reason I've had to adjust it any is that I've taken the scope off twice to to the reticle not being perfectly level. I tried to fix it, but it still was off so I sighted it back in and used it for a while, then finally decided to try one more time at fixing it. I had to sight it in again after that, but other than those two times it's always been dead on, and it's surprisingly clear for a $30 scope. Now it's not as clear or as good in low light as my $200 Burris, but it's pretty decent too and plenty good enough for hunting.
Infact, that being said is the only scope I've had go bad on me has been a Leupold, and I've used 4 or 5 cheap scopes. Plus about 90% of the guys I hunt with use cheap Simmons or Tasco's, and the few others use cheap stuff like Bushnell Banners. or cheaper Bushnells, or the scopes that come in package deals on guns. One or two use stuff like Redfields, but that's even rare. I rarely hear of any of them having any problems, yet 2 friends other than myself have had issues with Leupold's and I only know 2 others that have owned them.
