I bought mine about 4 years ago, after waiting and watching a while. I found on Ebay a 500series that had been a store display, ad had no box or chuck, but was complete with everything else, including carry bag, manuals, cd, etc. Got it for $35. I watched Ebay for a few more days, and got the 3/4 chuck which also goes down to 1/8 for $15. It took about a week to pay for itself, and over the 4 years since I bought it has saved me enough to pay for several of them. It really paid off when I put Helicoils in a few finals, both for me and for a couple of friends.
