I should have them ready to ship Friday. If you want one please just let me know... PM here or email to: jtoddshultz@yahoo.com. The current price is still $30.00 delivered to USA.
Dremel made a tool called the "Advantage" that had a collet to accept 1/4 bits. It was a weird combination rotary tool, router, rotary saw...etc. It had an completely different mounting design and I don't think it could be used with my style of rotary tool holder mount. Besides I don't think they even make them any more. I think it may have become the Roto Zip.
I do have the rotary tool holders and other items on my web site: http:www.midamericapool.com. I am adding more items so if you don't see what you want just drop me note and let me know.
