Jim I'm a confirmed catalog nut. I order every catalog I see so I can look at all the different tools and prices. Since I live out in the boonies I have to buy everything mail order. For woodturning 9 out of 10 times I get my tools from Packard woodworks or Craft Supplies. Other good places are Highland Hardware, Rockler, Woodcraft, Hartsville tools, and Lee Valley tools.
Of course there are a lot of individuals selling tools as well. I'm real fond of the Doug Thompson tools and a little more specialized but the Hunter tools are great for end grain hollowing.
