I like the Yamaha VX Deluxe, bought one last week for the wife because she has wanted one for several years.  We had a Yamaha 15 yrs ago and liked that one, they've changed a lot in 15 yrs.    If you have several grandkids a boat might be a better choice, the dilema we had with the first one is when all of their buddies came over and wanted to ride it.  They were 13-14 yrs old.  So we sold it so we didn't have to deal with it.  Now they are old enough we don't have to worry.
