I bought a used Hobie Revolution 11, that had alot of features + the inflatable tires for $1600. Which was a no brainer for me, I jumped on it, due to the fact I researched all the equi8pment prior, the wheels alone were a $200 investment. The Yak was in Excellent condition, outside of the sand scratches, but hey thats gonna happen, and paint didnt look all shiny, but these thngs didnt bother me. The equipment/Drive system was in Great condition. Thats what you need to look for in used stuff. Also If there is equipment added, make sure its not going to interfere with how your layuot would be. Again though, you can alwas fill holes, and move stuff. The New Yak, you have to take into account tax. So thats a hidden fee right off the bat. In My Humble Opinion.
Cheers
