Buy one, get it shipped to you. I have owned 4 of those now and I can tell you that you would have to be an expert cabinet maker and own a metal fabrication shop to build one of those.
They are fairly cheap too. I just sold two of the darn things to soulcon for around $60 each.
Also, Danny, I can't believe you built one of those! I see yours is a bit different than the normal ones though, as the normal ones use a lot of metal in addition to the wood.
