To be fair, I assumed we were talking about
new bikes, not a pre-owned Stumpjumper. And the bike the OP was asking about is a $260 bike. As far as doing tricks goes, you can't even find a new BMX bike for $260 unless you want one made of Hi-Ten.
You certainly don't need to pay $500 for a bike that's suitable for tricks though. I would NOT use the Trek 3 and 4 series hardtails that Joe mentioned either, but I don't remember paying much more than five bills for
this (new off eBay), and 99% of people aren't going to break that (and the other 1% knows who they are and aren't asking this question).
