I picked up one those flex coat kits on ebay a few years ago. Comes with stands, motor, and a few tools. Think I got it for around $100. The utmost folks hooked me up with a piece of old blank and some coarse sand paper to make a reamer, which was nice.

Unless you intend on becoming a rod building maniac I'd stay around, or under, $100 at least. You could probably get by for about $50 if you made your own stands and 'thread distribution and tensioning system'. Could probably fabricate something in an hour or two.

But then again sometimes buying a kit package is cheaper than the sum of the parts.
