New or used? Please help me decide.

Okay folks, here's the deal. A few months ago, I had planned on buying either a 2005 GSXR 600 or an R6. I really liked the red/black bikes in each model and both have very similar performance. However, just a couple months ago, I found out I'm going to be a dad in late May/early June (which is why I most likely won't be able to make the gap trip). Now, since I'm not married to, nor am I planning to marry the woman (we aren't even dating), I'm going to be paying child support. Yes, I will be the best dad I can be, and I love children, but this woman is not someone I want to spend the rest of my life with.

Anyway, before I found out this news, I knew I could easily afford a new bike, however, child support will put a bit of a belt on my budget (don't know exact amount yet). I had then decided to just look for a good used bike (no older than 2001, 99% sure it would be a GSXR) and paint it the colors I wanted since the red/black was not an option before '05.

BUT, I JUST got an unexpected 5K per year raise (today), so I'm thinking that will at least come close to covering child support. So, the question now is do I still buy used, or do I go ahead and buy new as previously planned?

What are the pros and cons of each? Any opinions (on the bike, not the child situation since I already know what I'm doing there) would be greatly appreciated.
