I'm sure you'll get a lot of input from everyone else about the boat in general. All I can offer is a 29 Scarab that I think is a good deal.
There's a dealer in New York that has a brand new 2001 w/ a 496HO in it for $69,900. That price is w/o trailer, but I think he is REAL motivated to sell! I have emailed a couple times about the boat. VERY motivated! FYI
Put a Whipple on it and you should be running pretty good.
Let me know if you want the link to the add and I'll hook you up.
