I have the wooden frame which I believe is called the Falcon frame that is one of the options in their packages when you buy the machine. The only problem I had with this frame is I have to go and purchase the metal conduit pipes for it and it was quite a task finding metal pipes that are really smooth for your machine to glide on. I ended up having to use a metal grinder to make the pipes smooth. If I had to do it again I would have upgraded to the metal frame which I believe is the Pheonix frame they offer. The frame itself is great and I have no problems with it or they way it functions, as it was just the metal pipes I had to buy where the problem.
