Have owned a 240SD and a 30 Sunadancer:
and people are right. It all depends on the usage and porpose of the renter.
As I currently own a 2006 260BR from Formula ( great seating) I can honestly say I have had fewer issues with this boat than my 240 SD. The boat is great and well powered and heavy enough for anything the lake has to offer.
Look for a model with the extended swim platform it gives so much more usable space for relaxing.
With lots of used invetory I am sure you can find a deal out there.
Good luck
