for more information on the saiga platform
you will get a ton of help from there
as for anything canted, make sure the weapon is unloaded and basically look down the rifle barrel up to see if anything is not aligned, it will be slanted, usually the sights will be canted (normal for cheaper AK's) can be fixed with a hammer or just take out the pin etc.. if the gasblock is canted don't even bother with the weapon.
that website has the cheapest saiga as far as i know, i know it's more money but i think it's worth every penny, i was going to get that rifle but i decided to get the saiga in .308, when i get a tax refund next year i will definitely get that AK or at least the one in .223.
you can expect 4-5 MOA out of the WASR typically, i have seen better and i have seen up to 8 MOA, you may get better with the saiga, 3 MOA but it will be more consistent, most people don't run optics (scopes) on a AK other than red dot so they can do better.
if you just want a AK style rifle, you should definitely consider the saiga in 223/7.62x39/.308, 223 starts at 400, x39 at 400+(for magwell conversion), and .308 at 600, i ended up with the .308 last week, shot it yesterday before i move onto modding the weapon, i was hitting 2" groups, around 3-4 after the barrel heated up, definitely a good purchase, it can do better, but i am satisfied.
Don't worry about the whole MOA thing, it's a stupid internet thing to get caught up with, most of us will never have real application for MOA, just get something that is in your price range and will go bang every time (basically what most AK's will do), if money is tight, it is a ok to good price for WASR, it will serve you well for a hog gun, home defense, urban combat (if you're into SHTF) or plinking/having a good time, if accuracy is an issue, they will do fine to 200 yards with a good shooter, hell i have even seen up to 400. the ammo is a lot cheaper for 7.62 x 39mm = more time shooting your rifle = more fun..either the wasr/saiga will eat any ammo,
another thing i forgot is the wasr has mag wobble but with tapco mags, they are very snug, if you don't have a converted saiga you can't accept normal mags for that rifle but there are aftermarket ("high cap mags"),
