Yes, NDS (DCI) receivers are outstanding. The Armory USA receivers are also very good. Those are the only two US manufactured stamped receivers I'd own.
If you're looking for a "stock" 7.62x39mm rifle, stick with a fixed stock weapon, the underfolders and side folders are very uncomfortable to shoot.
I'd avoid the Century WASR-10 series, which will be your cheapest route, unless you can physically examine the rifle for straight sights and mag fit.
If you can go up to around $600.00 or a little less, the Vector series of rifles would be my choice for an AKM.
You can get them in both wood or synthetic stocks.
The Century Arms Yugo builds have been getting a fairly decent rep, but again, unless buying from a known, trusted source (feel free to ask me if you find one online if they're known or trusted), it's best to hand pick them. Also, avoid the underfolder if you want to do a lot of shooting comfortably. The folders are great for getting in and out of a T-72, but they suck for shooting.
If you want a good 5.45mm rifle, try your best to find an Arsenal Inc. SLR-105A1. These are as close to a "real" AK-74 as is possible, and they are great quality. Since they haven't been imported in a little over a year, they're hard to come by.
You can buy a kit from Ohio Rapid Fire and a NDS receiver, then have someone build it for you.
The problem with the Tantals is that they are all kit builds, so quality is going to vary alot from builder to builder.
I'll poke around a little and see who will have some decent ones.
Atlantic Arms has a great rep and will stand behind anything they sell, so if it screws up they'll take care of you.
I don't have any first hand experience with these builds, but as I said, Atlantic will take care of you.
Hope that helps.
