Andy,
Before Hurricane Katrina I used the same Dremel tool I bought in 1985, 20 solid years! I cannot tell you or remember all the things I built with that tool. I did use it on 99.99% of every model I built.
I just got around to replacing it with a newer model - 400-6/90 400 Series XPR Rotary Tool Kit, it come with several different tools.

Dremel Stylus, (cordless version)
Scroll Saw
Drill Press Work Station 220-01 WorkStation
I think I use the tool at least 2-3 times a week.
Best tool I ever bought! You can probally see the tool in some of mu work shop pictures.
