Well, in the past, AK's needed to really be looked over before buying. There were a lot of kit builds by companies that had no idea what they were doing.
Now, your options are actually rather limited (meaning, you only have a few options if you want to buy a new gun off the shelf). That's good, because most options are fine. You need to look them over for fit/finish, but chances are, if you stick to the most common ones, you'll get a working one... WASR's, N-PAP's, Arsenals, VEPR's, DDI's, and Century's.
WASR's have CHF chrome-lined barrels, good fit/finish now, though still a bit rough, and they are fairly faithful to the AKM design. Good buys at their price point.
N-PAP's have a CHF barrel, not chrome-lined, and again, good fit/finish, but they have to use Yugo furniture and parts. I like them, I have an N-PAP underfolder, but I can't say I particularly care for them over WASR's... The proprietary nature is a turn-off. The new WASR wood is better too, if you like wood. About $600 for both the WASR and N-PAP.
Arsenals, SLR's specifically, have a CHF barrel, it's chrome-lined, its all brand new, and they come with polymer furniture (I really like), and a factory side folder. The fit/finish is excellent, and while they're expensive on the surface, consider what the actual cost to install a Bulgarian side-folder is, and apply that to, say a WASR... you're looking at the same price or more. Looking at $950 or thereabouts.
VEPR's are Russian, CHF chrome-lined barrel, RPK receiver, slightly heavier barrel, can take AK mags with a few minutes of filing, drilling, and tapping. The furniture options are a bit restricted, but the VEPR is an animal of its own, and the factory wood is gorgeous, so it gets a pass. Looking at around $600-$700 for a VEPR, $17 in parts to let it use AK mags.
The DDI, and Century's house builds, use US-made chrome-lined 4140 barrels. It's not as good as what comes on the other rifles mentioned, but it works. If you're not a high volume shooter, you'll never be able to tell or care. I would also like to believe that the Green Mountain barrels are also more accurate than the commie barrels, but I can't say. They're all new guns to the market, and while initial tests look great for DDI, it's still lacking a track record, and you're getting more for your money out of the others, just for the barrel quality.
I honestly don't think you can go wrong in which rifle you choose from a functionality standpoint. Canted parts are par for the course for any AK, Arsenals included, but that is cosmetic. So is fit/finish. But functionally, they will be fine.
So for you to decide what to spend on, look at features. Do you want wood, do you want a side-folder, an underfolder, do you want a side rail for optics, stuff like that. And then you can make a better decision.
