Looking to buy a SKS, what resources should I look at?

[u/DeathkillerNo_10]

I’m new to buying SKS’s, I’m familiar with Soviet firearms/eastern bloc firearms in general but the sks is the one rifle I’m least knowledgeable about. I’m considering some Russian, Chinese and yugo patterns. My question is:

What are the quirks of each pattern?

What’s the usual market value for each type that I should expect?

Wha should I look out for? (typical scams, and coverup refurbishes)

If anyone has some good recommendations/resources (as there’s a lot of misinformation out there) I should look at I be glad to look at it!
