Geo Hex and or battle mats

Does anyone have any experience with the GEO Hex terrain system? Or can you recommend any other terrain system?

I am getting my new and improved gaming room in order and I would like to get a new outdoor terrain system.

Thanks in advance.

Edited: I think I found what I want to use. For those gamers who are interested, check out:
