Where's the best place to get a plain jane p-grip converted saiga 12? I plan to add all the cool stuff later (upper rail, handguard rails, folding stock, etc).

This right here is the type I'd like to pick up:
http://www.atlanticfirearms.com/storeproduct1019.aspx

But I'm not sure if that's a good price or a good vendor. Atlantic firearms has been kind of unresponsive to requests in the past, and I think I've heard some less than stellar things about them.

This is close to what I want the end product to look like:
http://www.atlanticfirearms.com/storeproduct1156.aspx

But I want to get a stripped down version so I can figure out exactly which upgrades I want; unless someone happens to know where I could get a good deal on an already pimped out version.
