You can't go wrong with a Sunsation - from quality of build to customer service and support, everything you hear is true... I know first-hand as I owned one. Joe and Wayne - the owners of the company - are first-class, will help you out in any way they can and stand behind their product. I'd be sure to get it surveyed first, make sure the boat is as-represented and cover all your bases. Once you get to that point, if you can make the $$ work - and you are happy with it, buy it. From a brand standpoint, you will not be disappointed.
As Woodys said, OSO is a good source, as is the Sunsation web site - they have their own forum and you can get a TON of info there!
If I can help at all, let me know.
