re: Dremel tool suggestions
I have had a couple dremel tools, one black & decker, all used. After loosing tools in a fire I bought one online which appears to be the one sold by Harbor Freight. It is variable speed and also has the flexible sharft which you can use or not use. I like it a lot. I also have used HF's diamond cut off wheels and they are fine. They also have larger sized reinforced cut off wheels which are nice.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
