Well, maybe I got ripped off...my 08' Infusion was $12k including road-worthy trailer (value = $500 IMO), but in like-new condition. When I was shopping there weren't lower priced options in equal condition, just older boats that were more beat up for slightly less money. Infusions are still competitive, long boards or short, so $10K seems to be a reasonable minimum.

Maybe I would pay $12K for a 2010 Mk. 2, maybe, that is a bad year for Infusions. Lets look at a 2011 Mk. 2 then. I don't think you can get into that boat for less than $16K including trailer, if you're lucky. A new Mk. 2 is ~$23K. Two years old, you're looking at new sails, so $23K-$4K = $19K. Subtract a few $K for wear and tear, add a new trailer, and $17-$18K for a 2011 Mk. 2 Infusion seems about right. Trouble is a lot of boats on the market right now, might be hard to move that...
