Seem to recall RIB International magazine tested Selva's a couple of years ago and were less than complimentary about the handling. They may have a report online at
www.ribmagazine.com
Are you definately after a new rig or would second hand be OK? If the latter then there are loads of boats around in your price range.
One recommendation I would make if you want to do any really serious Ribbing (& I would include the club rescue in this) is to go for jockey seats rather than benches every time.
