That's kinda what I was thinking, too. By the time you get the "RIGHT" materials to build a frame, take it down and have a custom top fabbed up for your frame and all, and hope you're satisfied with it, I figured it would be more than that...
I'll probably try to get one of these in the next few weeks, after I get the rest of my funds for it, unless a used one presents itself to me - which I highly doubt...
And get one before they end up back off the market again for whatever reason...
I like the overall design of it. I guess we'll see what happens...
