Rey - you might consider contracting wtih a local welding shop to build it for you. Get the plans and take it to them with a couple six-packs.
Craigslist is a great place for tools....there were 4 KMGs up for grabs in my area just a month or two ago...
It's also a great place to find welders. Look in the Barter section.
And maybe there might be someone here willing to put one together for you. If I had the welding skills and time, I would do it (and make one for me at the same time).
I'm not crazy about the idea of the no-weld plans, though....*shrug*
In all, you'll probably end up spending $400+ since you'll have to buy the pulleys new (can be found at surpluscenter.com)
Something to consider....
How come nobody told me about the "used KMG" pricing rule?
I knocked nearly $1000 off mine when I unloaded it.
Of course....I beat on it incessantly for several years...wasn't very pretty anymore....:foot:
