You should be able to get Porter-Cable bits at Lowe's or HD. Same with DeWalt bits. Same with Bosch. The Craftsman bits aren't that bad either, made by Porter-Cable or Bosch, as are the Profesional series Craftman routers. I have the same group of bits that I have bought over the last few years. I bought them all at HD or Lowe's and bought them individually rather than in a set. The only bit I've had to replace was a spiral upcut that I just plain wore out. The spiral bits are high speed steel rather than carbide and I had some ncidents with it thanks to my cheap plunge router. Even after walking out of the collet on at least 5 occassions and into the aluminum table I was working on, or slipping into the work past the cutter edges and heating up to the point it was causing the wood to smolder, it still lasted my through a lot of boxes, mid range baffles etc, over the 2 years I used the first one. Definitely got my $20 worth out of it.
