I have the chance to pick up what seems to be a pretty decent deal on a pair of 99 yamaha xl760s for $3k with a dual trailer.  Given that they are in good shape, is that a good price?  They are a friend of mines and have been in storage for 2 years, what should I look for when I go see them?  I've never owned any type of pwc or watercraft before, and this seems like a reasonably inexpensive way into something.
