Congratulations, and welcome to the comrade life. It's pretty good over here.
I'd start by exploring this subforum and seeing what the AK hive mind has to say. This topic pops up as a new thread pretty regularly, and the same folks (myself included) pretty much copy and paste what we've all said before. These current times are a bit different than "normal" times, but most of the suggestions remain true. The Romanian WASR-10 will get you everything you need in an AK, unless you absolutely need receiver dimples. Chinese MAK-90s get you dimples, but not much more in my opinion. You'll also more than likely forgo an optic rail just in case you absolutely need one of those. They are both solid guns in my opinion, and either will suit you just fine, although you'll probably save a bit of coin by going the WASR route. Having owned both, I'd go with the WASR personally.
What's the M70 variant you are looking at? Is it one of the new Zastava USA factory ZPAP builds or an older Century-cobbled M70 variant? For these I currently own both and they are both decent guns in their own rights. If I had to grab one it would be the ZPAP hands down. Note that Yugo/Serbian furniture and many parts are not interchangeable with the more combloc standard WASRs, Russian, Bulgarian, Polish, Hungarian, etc. AKs.
In the past many of us - again, myself wholeheartedly included - tried to steer folks away from American made AKs such as IO, Century (their imports are usually fine, but in-house guns such as the RAS, VSKA, and C39 are junk), Riley, and early PSA models. That said, PSA has really grown and evolved since its first questionable gen-1 PSAK, and I wouldn't write off their newest models. With PSA you also get a lifetime warranty and from what I understand, some pretty decent customer service with good communications.
Do you want an AK just to have an AK? What do you intend to do with it? How long do you intend to keep it? Do you intend to buy more than one? Have you ever shot one? Do you have any 7.62x39 already in house or will you need to invest in ammo, mags, spare parts, accessories, etc.?
If I had to suggest a single AK for someone new to the "platform," 10 times out of 10 I'd suggest a WASR-10 with a case of Wolf ammo and as many surplus steel and/or surplus bakelite and/or Bulgarian Circle 10 polymer mags as you can get your hands on. Cugir's relatively affordable take on the AK will do literally everything that a milled Arsenal, Russian VEPR, or $2,000+ "custom" Krebs carbine will do, and you'll have enough money left over to fill your Dacia trunk full of ammo.
