One of the key things to look for when buying old used items is pitting. There are many with little or no pitting at all and it becomes obvious from the photos. DOnt buy if you dont get a nice closeup of both sides.

Learning to sharpen is something you will need to spend time on and when you get up in the AM and shave with your chisel before you head out to the shopm you know it is ready for work!

If you can get yourself a Swan, White or Whiterby you will be happy and should easily be able to get each needed size under $50.
