If I were you I'd look at as many different RIBs as possible and just like buying a car you'll decide what's right for you and what appeals to you regarding looks, speed, handling, economy etc etc.
A good place to start is www.boatsandoutboards.com
where you will find 100's of ribs for sale. Note a few manufacturers names you like the look of and visit their web sites from where you'll learn more and more. After that go back the the "for sale" sites and take your pick.
It's the bottom of the season so now's a good time to buy and a bad time to sell so if you see something you like the look of don't be afraid to knock a grand off the asking price, you never know the seller might just say yes.
Happy hunting.... let us know how you get on.
