+1 Corwin-Arms. Martin know his stuff when it comes to the Red Rifles. He will not sell a bad one.
The price variation for the ones he has for sale ($198-$277) will have nothing to do with how well it shoots or how accurate it is - he hand picks every one he sells, as far as I can tell - but will be depending on how collectible/uncommon of a flavour it is.
For reference: When I asked for a "hand select" 91/30 from him earlier this year, it still only cost me $195, and it was a non-refurbished, near mint, 1938, all matching numbers, with even a numbers matching bayonet. I have no idea how he gets hold of quality milsurps like what he carries, yet manages to keep the prices so reasonable.
Ask around, you'll get similar references for Corwin-Arms from pretty much any CGN'er who's dealt with him.
