I gave up on Dremel a couple of years ago (at least the plug in variety). Brushes are one thing, but switches that regularly die are sort of unforgivable in my book. I decided to buy a Proxxon and give it a try -- with mixed results. The Proxxon has now had nearly daily use for a couple of years and it is a decent tool. However, about a week after purchase it refused to turn on. Yes, I could have returned it, but I instead took it apart for a quick look. I found a bad connection where the AC power connects the the circuit board. Fixed that and it's been a champ ever since. I love the fact that it has an adjustable chuck and truly minimal side to side play at the front bearing. This thing now has hours upon hours of use, has been dropped several times, etc.
I also have a Dremel 8100 that I bought for pretty much one operation at a separate bench. It's of the rechargeable variety, and therefor handy to have around for non-shop related projects. From day one it's had the sloppiest front bearing one might imaged. Unless this one -- from new -- has been an exception to the rule it would be useless for something like inlay work.
So, thumbs up for Proxxon with some quality control reservations. I would buy another Proxxon.
Thumbs down on anything Dremel makes these days. This is sort of sad. If you've taken a Dremel apart as many times as I have it become obvious that a far better tool could be made for probably the same amount of money if anyone actually cared.
And, our CNC machine sports a full-size 1/2" Porter Cable router motor. It's now far outlasted the Rigid motor it replaced (which ultimately melted its plastic brush holders). The smallest thing I'd recommend for any CNC work would be a laminate-trimmer sized motor, and I'd only use one made by Porter Cable. Porter Cable still makes their stuff in the US. It's not the prettiest nor does it come with all sorts of useless bells and whistles, but it's well made and tough in my own, humble experience.
I really hate to say this, but: I frequent Harbor Freight these days. I have discovered that the cheap stuff they sell is not just a whole lot cheaper than the main name brands, but in most cases (not all) is just about as well made and lasts just about as long. I would love -- and I mean really love -- to be able to buy a well made, reliable tool from an American-based company (even though it's made in China) -- but in my own experience they don't exist anymore (with the exception of folks like Porter Cable). I would definitely pay more, and for some tools a lot more. I just don't represent the market they cater to.
