I have one set that has lasted since 1997. I did have to replace the tires once, but that was well worth the investment. In hindsight, I'm sure that I probably could have gotten away with just tubes, but my dealer had a spare set of tires at a fire-sale price.

I have yet to see a set of home-mades that work as well as the Cat Trax or Roleez. Most of them wind up to be extremely heavy, and/or dig into the sand too much.

$250 for a used set is about as cheap as you will ever find them, and worth every penny in the long run.
