OK, this is very puerile, but:
In England, "bummed" is childhood slag for gay sex, so "bummed in az" struck me as funny somehow.
OK, back on topic.... You don't need any mods to do lots of tricks, and only a few small mods to start learning most of them. Just because all you see on videos is aerial tricks, doesn't mean that there aren't a bunch of fun tricks that you can learn. They're fun to so and your friends will love watching.
Think about subs (jump, spin), bulldogs, 360's, rodeos, fountains, all sorts of other hood riding tricks, monkey jumps, 50-50's. You can start on all those straight from stock. Don't be intimidated by the adrenalin junkies who have forgotten (or never knew) how much fun it is to learn and master finesse tricks - just go enjoy your ski.
And with footholds you are all set to try anything anyway. It's a shame to be unhappy because you can't afford more mods when I bet you haven't tapped into 10% of the things you can do with the ski you've got.
