I've come to the conclusion that the Dremel tool line just dosen't cut it anymore. I have had mine for a couple of years now and it's just worn out. I use it quite a bit not just for razors but a bunh more things that I do. I do use the flex shaft all the time and I'm tired of it being under powered. I have been looking for a lifetime replacement and this is what I found. The Foredom TXH series, I belive that this setup should be versitle enough to last me a lifetime.

Just a thought for anyone wanting to get a Dremel and you are serious about restoration work consider something like what I listed here.
