Depends on your expectations and intended use. If you plan on shooting a lot, for the money, Shilen or Excaliber. Nothing wrong with a Criterion or McGowan either. Bartlien, Kreiger, Brux and several more can be had also if you are planning on competing at a higher level. Bugholes.com

Shaw's can be accurate but the quality of the bores are in a different League than the others mentioned. Cleaning is required more often. I think I would buy a Wilson before a Shaw. This is my opinion based on experience.
