I agree with all of the preceeding posters. You will find that you really only use 4 or 5 attachments for your razor hobby. You may use several other attachments for other activities but the fact is you really will never use most of the attachments found in the larger attachment sets. The best bet is to order a dremel pack that comes with a reasonably sized attachment set (say 50 or 70 pieces) and use it for a while before you spend the money on a large collection of attachments that you will most likely never use. If I were you, I'd hold off on getting the new dremel until you've received Bill's cd. If you really can't wait, drop Bill or one of the other restoration experts an email and ask for their recommendations (before you buy). Cheers and best of luck....
