I recently found myself needing a new flex shaft. I checked out Otto Frei (advertised in the September 2007 Art Jewelry Mag on page 9). I was very happy with what I saw. I was able to purchase a Foredom SR series 1/6th horsepower reversible flex shaft for much less than I thought I was going to have to pay. They also have findings.
They were very good about the percentage off coupon mentioned in the ad and the website is very easy to navigate. My invoice was dated 8/21 and it arrived on 8/24. Everything was in good condition. Have some fun and check it out.
