Place to find used turboprops?

Hi,

This is my first post of many. I would be glad to be useful in things I can help as structural and fluid dinamics threads, but now I need help from the salvage guys who knows every corner of the aviation market.

I am searching for good / used turboprops at a fair price. Mostly TPE 331´s. And PT6A as a second option. Do you know any company where I can find any?

Thanks!

DB
