Looking for a used bike.. not sure which ones to look at...

Yes it's a typical post that all people ask, but I'm limited on time so I'm hoping you can help me narrow my choices down so I'm not trying out a bunch of different bikes.

Here's my stats...

Height: 5'7"
Weight: Dieting plan to be 150lbs, currently 180lbs.
Inseam: 32"
Age: 32
Price Range: <$6500

Previous Bikes:
- '99 R6 (Stolen)
- '02 GSXR-600 (Stolen)
- '04 GSXR-750 (Beat them to it and sold it.)

Things I liked about each bike...
- I liked the size of the R6, I have a 32" inseam and although it was my first bike, I felt much more "in control" on it. I didn't like the way the R6 cornered, it always felt loose to me, like I was pushing it into the corners, that might have been me being new to riding.
- I didn't like the GSX-R600 size it felt very wide.  I liked how the power seemed to come on earlier in the RPMs than the R6 but ultimately, it just felt like a hoss to me.
- The size of the 750 was an issue for me just like the 600.  However, I loved the way the GSXR-750 handled in the corners.  It was the nicest handling bike of the three and that ended up helping me fall in love with the bike.  When I was out cruising around back country roads or on the track I felt at home on this bike.  However, the size and feel of the R6 was something I never forgot.

Why do I want a bike?
- I've held off just about as long as I can... the itch is too strong.  I don't plan to do many track days, with it, but I would hate to not have the option.  I fear that once I have the bike I'll want to hit the track.

I hope that helps answers some of the basic questions, hopefully I haven't forgotten anything.  As I mentioned, I don't expect to get a solid answer, but I do hope to limit my options and then try them out.  Thanks in advance!  

this sounds more like a diary entry
