Here's a link to a newer version of one of mine http://www.sears.com/sr/product/summ...id=00961087000  nice url huh??  If you look around you can also find some that run off of small power packs so you don't have to fight the cord.  Hella lot's of help.  They can cut, grind, polish, sand, and make an expresso (okay, I'm not sure about the last one but I know it'll do the rest).  Good investment if you really like.  And we're all geeks to a point.  In fact that's a good news site if you get a chance www.geek.com.  Happy moddin
