The busa will probably minor changes next year the only benifit i see is finding a left over 04 and getting a better deal, the 1000 is scheduled for quite a few changes from what i understand. it just depends on what you want i personally would look into 04 zx10, 04r1, or hold out till the 05 gsxr1000. no matter what you buy as long as it isnt a honda youll be doing good
