and actually posted my review on the Amazon site. I've been happy with the saw - it certianly meets all of my needs. However, if you do end up going that route, plan on adding a PALS system since getting the blade into alignment was almost impossible without it.
Overall, it's a great value for the price Amazon is offering - but I don't think you are going to see a massive upgrade from your contractor saw. The only comparison I have is a 15 year old Sears contractor saw that my father has in his shop - so it is difficult to compare. However, this isn't a real cabinet saw and if that's what you are looking for it isn't going to meet your needs.
Let me know if you have any specific questions or need some pictures, I'll be happy to help out.
