Might check stores such as Rural King, Orschelins, etc. I just got started and bought Bridger dogless #2 offset. Use Wolf Fang earth anchors. Unless you find a screaming used buy, probably better to buy new. Hoosier Trapping Supply is also good for online.

I bought some Duke #2 dogless and while a couple bucks cheaper, the jaws would not lay flat. They will work but other brands seem to be better quality.
