I have a 2004 Ribeye 550 with two double jockey seats and a rear bench. Agree with all the previous comments, I'm made up with mine.
I moved from a 4.2 Aluminium hulled rib and the difference is huge. The feel with the 550 is one of reassurance and confidence although it is still manageable on a trailer with two people pushing and pulling if needed.
I don't think your budget will get you a 2007 model though, but best of luck, you wont be disappointed.
I am looking for a bow cushion and the three backrests for the rear bench seat if anybody out there can help
