no experience: SV650s
Some experience: CBR600 F2
Experienced RideR: Whatever you wish.

I don't think either of those bikes wil suit your needs for commuting. I'd say something like a '99-'00 F4 like Rich said, comfy as hell, or even an older than that CBR (F2, F3).

Another reasonably comfortable bike is a '99ish YZF600r (not an R6).

All of these bikes are more than capable of walking any of the other bikes, its all rider.

Ugh, I hate these threads. =[
I should note, I've got nearly 40k miles under my belt now; on bikes.
