Big difference.  The 2008 is essentially the same as the 215 Wake with the smaller engine.  (I prefer the smaller engine from a maintenance standpoint, as it does not require premium fuel, and you don't have the supercharger to potentially go out.)  The 2010 is the same engine but a completely different hull and configuration.  The 2010 does not have any of the ballasts either.  The price of a 2008 back then was $10,000+.  I'd go with the 2008, given they are both brand new.  I am biased, as I own a 2008.
