I bought my beloved Dremel tool 30+ years ago and happily used it for many years. Then, a few years back, it accidentally got left out on our (covered) patio, and rusted. I've never replaced it. My questions: If I were to replace mine, are the modern ones not junk? This, of course, is a subjective opinion, but I'm interested in tapping the collective experience of whether they are still worth having or not. Litmus test: if I were to use one for 15 minutes each day and it failed in a year, I consider the thing junk. Obviously, they're not built for continuous duty, but with occasional use, mine ran for a long time (I also didn't abuse it). If the answer to the previous question is "yes", what model would you recommend? I lean towards the fixed speed ball bearing model, as that has fewest things to break. If you recommend the variable speed, can you explain what uses the variable speed is useful for? Please ignore the case of running wire and synthetic brushes. Can you recommend where one can be purchased in the US without all the crud they want to sell with it (i.e., the "kit", which I find about 90% of the stuff in it worthless)? If they are considered junk, can you recommend a replacement from a different manufacturer that is not junk? Cost is not terribly important, but staying cool in the hand, light weight, and good reliability are important.
