I guy in our club has the spidertrax 1/4 eliptical and it is beyond awsome. In fact it would make people stop in there tracks to watch it flex. That was the most pictures I have ever seen taken of one rig in one day by strangers than I have ever seen. Unbelieveable!

The last I talked to Mike, the kit price was gonna go up. To how much I don't know. He is a hard guy to get ahold of but I would deal with him direct instead of a middle man.
If you want it for on road go YJ springs. That would be your best rout with out a dought. They claim 40" of flex with missing links. It will cost you though. There is a lot of extras you have to buy besides the kit.
