Hi Mike! I had the DW745 for approximately three months. It was my first DW purchase (I own mostly Makita, Festool, and Bosch), and I was really bragging it up to my coworkers, because I think it fills a very underdeveloped tool category: small, benchtop tablesaws that are small enough to be carried with one hand, have standard sized miter slots, and a reasonably accurate fence. My idea was to use the 745 for ripping framing materials and smaller repeat rips, and use my TS55 for breaking down sheet goods and precision cuts. Anyways.....
Ok, so I had it for roughly three months and I was really liking it. My coworkers and I were replacing all of the soffit and fascia on a house, and I was using the 745 to rip 3/8" plywood to size and 1x cedar fascia. Unfortunately it was pretty cold outside (maybe 10 F or so) and snowing. So, the fence adjustment knob (made of plastic) eventually cracked due to the cold, and the rack and pinion system got clogged with snow and ice and basically fell apart. We were even trying to carry it inside between cuts. Even though it was out of warranty, the manager at the local DeWalt service center was nice enough to take it back and cut me a check for the value as a customer service gesture, which I very much appreciated.
I don't mean to dog on the 745, I think it's a neat saw and fills a niche that few other benchtop saws come close to matching. My concern with the design is the kind of plastic that is used on some parts of the saw. I've worked in temperatures down to -20 F (that's -28 C), and my concern is that the problem I ran into earlier with the fence adjustment knob might resurface in cold temps. I'm pretty careful about taking good care of my tools, unfortunately sometimes working conditions can be tough, and I didn't want to tempt fate with another 745. So, in the meantime I'm back to a Makita 2703, which matches the portability of the 745 but lags far behind in terms of accuracy and useable miter slots. Right now I'm just hoping that Bosch or Makita comes out with a competing product to the DW745 so I can do a comparison.... (Are you listening Bosch and Makita?.....) If they don't come out with a competitive product in the next year or two, I might consider going back to the DW745 and simply modify or fix parts myself if they fail....
