The WASR's and SAR's are not bad AK's, and are very serviceable guns. They may not be as pretty as some of the others, but they do work, and work well. I'd put either of mine against any of the others. I have yet to have an AK with a "bad" trigger. I've had one that had slap, but even then, it was still a good, but painful trigger. All my AK's have had nicer triggers than all but one of my AR's, and that one is a match trigger.
I find it kind of interesting that the milled receivers are now all of a sudden supposed to be so much better than the stamped. They were short lived on the real guns and everything since has been stamped, and without issue. They simply started "marketing" the milled to the US market. All you have is a heavier gun, not necessarily better. I have yet to see one shoot any better.
As far as WASR mag wells, the early guns had some issues with the mag wells not being done properly, just like the early SAR's had some badly canted sights, but last few I've seen were fine. I would check the fit, but I dont think you'll find them as bad as you keep hearing. All of them will show some mag wobble, WASR or not, and its more the mags than the gun.
One thing they all pretty much need, is the mag releases edges "broken" with a jewelers file so they release easier and smoothly. The mag release is a stamping and has sharp edges from the process. The sharp edges tend to grab the mag and can make it difficult to release.
As far as the Saigas go, they can be converted back to their original configuration. Krebs and others do a pretty good job of it. Personally, I think the converted Saiga's are the cream of the crop when it comes to the AK's. Your basically getting a true Russian AK, made by Russians, once converted back.
