nsx, i'm assuming you have ridden a sportbike for some amount of time, so i won't bore you with 'sv650/msf/little bikes will make you faster' talk. but if i'm wrong, read small bikes kick ass
the dependability issues you refer to are mainly, well, crap.
the gsxr won't have the tranny problems the 750 has.
the r1 has the cush drive and hub problem, but should be fixed by now. even if it's not, i talked to chris at fcycle.com (a parts dealer) and he bought rc comp rims for his. there is such a high demand for r1 wheels that the new rims didn't cost 'that much'.
honda does have a great dependability rep, but it's not a valid reason to buy one.
now if i was picking, the r1 would be sweet, but it is uncomfortable, worse than a 916 (imo).
the gsxr (well i own a 00 750). but then everyone wants to talk about how cool your bike is and all that (it does get annoying).
then there's the 2001 929. i was looking at it in yel/black and i have to say it a looker.
my girlfriend won't ride on the back of an r1 rider seat is too long. she no fan of the gsxr, so maybe the 929 would've been a better choice.
