We like the woven plastic also.
Some people tout using indoor outdoor carpet. It does last about forever but it is horrible to roll up when dirty and wet and is difficult to store in that condition.
The woven plastic drys fast, cleans easy, and is easy to fold up and store.
I have found that the really cheap ones (less than $40) don't last very long and that the ones that go for $50 to $60 last longer.
Right now ours is about four years old and since we are full timers gets a lot of use. We got it in Quartzsite and paid about $60 for it,
