Friend in town has one, he loves it. If we didn't buy the Thomas and now the Gehl we would pick one up in a heartbeat. Might actually get one here soon since the Thomas burned up, it'd be really handy to have to move chunks and brush in places the Gehl can't get too and get them to a staging area where we could move it with the Gehl.
As far as making your own vs. buying it, personally, I'd buy one before making one. No need to steal another hard working mans idea. He came up with all the little things that make this cart what it is, and personally it wouldn't feel right building my own modeled after his. That's like instead of buying a Wraptor I get the plans for one and just make it myself, without Paul ever seeing a dime on money from me. I don't think any members here would do that to Paul. We all know how much money and time Paul put into it, and I'm sure he has a lot of pride in it as well. I have a shit load of respect for Reg, talked to him online and at TCIA, and even if he doesn't see any profits from the gear he came up with for Stein, he still has a lot of pride in the fact that he came up with it, its his invention. And personally, if I created that cart, and I saw people fabbing it up on their own, copying the ideas that I invested all my time into, I'd be pissed as well.
