At $65k, I think I'll wait until Christmas-time to ask for one. :) Best regards, MikeG ---------------------------------------------------------------------- Mike Gilmer - Galactic Stone & Ironworks Meteorites Website - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone EOM - http://www.encyclopedia-of-meteorites.com/collection.aspx?id=1564 ----------------------------------------------------------------------- On 3/10/11, mail at mhmeteorites.com <mail at mhmeteorites.com> wrote: > I have a photo of a multi-wire saw we sometimes use on Kerfindustries.com (a > business of mine).
