The Foredom tools are probably the all-around best for professional use but cumbersome to move around a lot.
We had on here in the lab but it was tossed during a cleanup.
Most of my power and bench tools are Craftsman. With a family member employed by Sears, the discounts made it well worthwhile.
My only complaint about Craftsman is their rechargeable tools. Seems to be a bit of a crapshoot but, for the most part, the batteries are not up to the task. I've had a few Craftsman rechargeables and all but one were tossed.
Both my Ryobi and Dremel tools were fine and the wear-out was only after many years of good use.
I have owned many Black and Decker tools and NEVER experienced a problem. So, I figured, why not try their Moto-Tool? I guess we'll just have to wait and see how it works out.
I've been using it every day since I bought it and so far, I'm really pleased. But, time will tell.
