What is the best Dremel for under $100? I'll be using it to sand and polish plastic and metal (restoring brushes/possibly straight razors)?
If you're working at a bench, you might consider bypassing a Dremel entirely and going straight to a flex shaft tool, which is what jewelers and watchmakers use. I bought one several years ago for my bench and hardly ever use my Dremel anymore. Foredom is the industry standard and can run a few hundred bucks or more. If I were in the market for a flex shaft today I'd probably take a look at the Grobet:

These also pop up on eBay occasionally.
IMO, the flex shaft tool has more torque and is a lot easier to control than the Dremel. But, as Matt points out, you can get a decent Dremel for far less, and spend the difference on other tools.
Thanks for the suggestions. Unfortunately I don't work at a bench.
What is the difference between the 3000 and 4000?
Really? I wouldn't think that Dremels were made to the sterilization standards of hospital toolsI was given one by a friend who works at a hospital, they throw them away after each surgery
Mine is pretty old, but I have the Dremel model 395 Multi Pro. It is 1.15 amps, and has a variable sliding speed switch from 5,000 to 30,000 rpm.
-I would never consider one that does not have fine adjustment for the rpm.
-I would get the quick change collet also. Makes changing bits easy.
But what do I know, they are probably all quick change now. I've had mine for probably 13 years.
Thanks. I don't think the new ones are quick change. Dremel sells a "multipro keyless chuck" to quickly change accessories for $5.
