For $40 its not bad considering what type of items you're getting. Personally speaking? IMO (coming from 11+ years of paintball and tournament play), you prolly should have gone with something a bit better in regards to quality. paintballgear.com usually has alot of closeout items for cheap. Plus, $30 for that mask? Definitely not. $20 for 9oz tank? No way.
I've found that more often than not you really get what you pay for, and some companies just don't offer good quality in their products. Viewloader is good at making hoppers...that's about all I would recommend buying from them. Not trying to rain on your parade, just giving my opion...pbnation.com forums is a good place to find people selling new/mint items for cheap too.
Was it a good deal? Yeah prolly, but if you end up finding you like the sport and staying with it, you'll find yourself looking at buying another marker for sure.
