i was spending $1k/year on the game. i stopped at the one b4 urza's (tempest?).
i hope it's not $2/booster?! when i was buying, it was straight from a dealer, so it was like $50/box.
as for hacking, closed bnet at diablo II was more or less cheat proof. and when they found the hack, the corrected it and killed the advantages of the hack. (tho i hear that a new hack happened recently on bnet.)
i might get back into it, depending on pricing. but only lightly at first till i'm certain it's hack resistant, and when wizards does find a hack, see if they will undo all the advantages.
wished they would just give u all the cards and pay a fixed price, like Anarchy Online. But that would kill their business model.
