Thank you gentlemen! Some great advice here. I found a used Delta on Craigslist that looks interesting, but I need to find out if it is a metal or wood saw. My takeaway from this thread and another conversation I had today, is that the saw has to have the speed variability to handle metal. While I'd love to have a big industrial unit, it isn't really in the cards for me. I'm thinking something that's about 10 inches and can accommodate metal will work pretty well. The goal is mostly for aluminum.
