Zander said it best. Ive heard the I20s are having an awesome come back, which in part can be a very good thing.
With your budget you should be able to afford brand spanking new.
A quick FYI in April the Alter Cup will be held in Gulfport FL. There will be 10 F18 Capricorns for sale at a cheaper rate. Cant go wrong with picking up an alter cup boat.
Good luck with your purchase.
