If you look around you can get a nice one for under 200Nice! Now all I need is a radial arm saw!
If you keep an eye on craigslist, you can often see one for under $100, including the stand with casters and with a work top. It will certainly need fine-tuning to get everything plumb and square once you set it up, and probably a lot of elbow grease cleaning it up, but as long as the motor is good, and the trommel can lock securely, then it can be a good tool. In my view the old Dewalt cast iron ones were the best for square and consistent performance, but my old Craftsman works quite well for cutoffs and angles as long as you take normal precautions with such a saw.If you look around you can get a nice one for under 200
