Check out the Dewalt DW744 table saw. It is heavy for a portable (64 lbs) but it is a precision saw. Local Home Depot currently is selling it for $399,usually $499. (It lists for $956.) Also Tools on Sale has it for $549 including freight if you want to buy through the mail. For years I have used a radial arm saw in a garage "workshop", but it was a hassle without a mobile base which I just added. The quality of bench top tools by Dewalt and Delta is very good.
