Yeah I tend to scour Craigslist and local estate auctions for equipment and stuff I could modify. MPLS has some decent used equip from time to time, as does Duluth, but you have to be patient, and ready to jump when something comes up. There are some other good DYI suggestions people have made here. I have made a Flat lap for thundereggs and agate geodes with a 110V motor, an arbor adapter to convert my motor shaft to a threaded end that accepts angle grander attachments (5/8-11) and bought a 7" Velcro head and silicon carbide sand pads. Works awesome. I got the motor for $20 on craigslist, and everything else cost less than $60. Its basically a 'Richardson's Ranch Thunderegg polisher' clone. Richardsons Ranch uses a 3450 rpm motor, which I have, but I may switch it out to a 1725 rpm as it gets the stones hot quick.
