Newbie here too. I've been riding for 3 seasons now, and I think that I can finally upgrade.
I currently have a '99 GS500 which is way to small for me. It was a perfect learning bike though. I've ridden quite a few bikes including Kawi ZX-6, Yamaha R6, Honda VTR 996, Honda VTX and a couple hawgs. I feel that I do have the skill and assurance to upgrade to the Gixxer 750 with probably a large learning curve, but I won't get a 1K because it just doesn't fit right.
I've been dreaming of the 750 since about a month after I bought my bike new, just because of the way it fits. The 750 Suzi is one of the few bikes that I feel comfortable on. I'm not in it for the HP or wheelies or stoppies. (for now)
I have also been shopping for it since I bought my bike also. In the midwest, the cheapest place that I have found it advertised is Chicago Cycle Center
www.chicagocycle.com I have seen thier prices bordering low $7000's at the end of the season with the 600's just below that. I haven't asked around to see how competative the local dealers will be, but that may be the best way to go. Plus anyone outside of a 30 mile radias can get a $50 gas certificate.
But, I'm still searching. Haven't figured out when yet but just thought I'd throw in my 2 cents.
