A few weeks ago I accidentally pulled my old Dremel off the bench. It missed the floor mat by an inch or so. Broke the Bakelite housing. It's a Dremel 100 that my father bought in the '60s. Sad day. I ended up buying a Dremel 4000 and I really like it. Good balance, much more powerful than the 100 and I like the variable speed much more than I expected. I'm still learning about what speeds to use where. Oh, all the bits and bobs from the 100 fit in the 4000 so I'm well set.
BTW Package deal at HomeDepot was better than the one on Amazon, counting content, shipping and taxes. And HD is on the way home from a trail I use a lot. Toofer.
