Cheap Red Dots are a tricky thing. Some like BSA or NcStar are complete junk. Some like Aimpoint and EOTech are expensive, but worth the money if you're going to use the gun in a situation in which you need the extra stuff like durability to getting knocked around, night-vision compatibility (on the models that support it), etc.
It seems as if this question comes up every so often and we started a thread a while back comparing some of the cheaper alternatives that were actually decent quality. I'm a fanboy of Primary Arms - they've done me right and I own (and have owned) several of their optics - they work like they are supposed to and they are actually weapons-grade and not airsoft-quality (like many of the other cheaper options out there).
My next choice (on a budget) would be the Vortex Strikefire or Sparc - both are good optics at a nice price.

Oh, and that moving dot - its doing what its supposed to do - that's why holographic or red-dot optics are preferred over etched reticles - you just put the dot over the target and the boolit follows - no matter where in the optic the dot is (if your red-dot isn't doing that, then throw it in the trash and get a better one ).
