i'm about to buy a table saw for general do-it-yourself useage. any advice on what size and price range? some of the inexpensive ones surely cant do the job, but budget is a concern. i've seen cheap ($149 delta at home depot)to expensive, but i dont want to be "penny wise and pound foolish" ! i often am guilty of over buying, but i dont want my tools to be the weakest link. any advice will be appreciated.
