Welcome, FTD. You should be able to easily find a good used F4, with the new '01 F4i having been released. Aside from the cost of replacing/repairing plastic should you go down (and I don't mean to jynx you by saying that), the F4 should be a great first bike for someone with your experience. You'll probably get a better "comfort factor" with it over the ZX7R. Good luck, and keep us posted.
