The cheapest ones you will find that are worth using, and very good actions at that are Czech Vz-24' s and 98/22' s- same action that could be had for well under $100. You can also get a Yugo K98 refurb for around $100 which might be a bit easier to find scope mounts for- the rear ring on a k98 is a bit flatter than a Czech 98. I can' t rememebr the name of the company off hant that sells them though. Stay away from the yugo m48' s- they require an extractor cut to be made in the narrel- like in a win model 70- but the action is 1/4" shorter than a standard 98 action, making it difficult to find a decent stock to fit the receiver.

I would stay away from the turk actions, as they are not up to the quality of the stuff made by the Czechs, and are threaded for a small ring barrel. There is one neat thing you can do with them however- you can buy a new surplus 6.5x55 swedish barrel from Samcoglobal for around $50 and it will thread into the turk action- but if you want to go this route, its probably better to spend a few extra $$ and buy a 96 swede to sporterize.
