I think you may need to watch for specific Lines or Models.
In my opinion, higher end Stanwells and Savs are both great buys, especially in the estate market. They're well designed, executed and finished and almost always smoke well.
Good luck with that. Every estate 320 I find shots through the roof price wise. I have one but I bought it new. They have a line called "Antique Shell" Rusticated finish, it is a seconds line but smokes the same. I got mine for just over $50, Pipesandcigars usually carries them, though they go out of stock quickly. I would love to get a 320EX. It would be like a big brother to my current 320.I'm still waiting for the perfect 320 KS (large author-style shape) to come up for me to purchase.
