Welcome to the group!
Lots of good info on this site. Also lots of opinions.
Don't be afraid to ask questions. Remember there are no stupid questions but there might be some stupid answers from people that forget that they were new to the hobby at one time. Better to ask about a specific AK variant first and hear the opinions pro or con than it is buying one and then asking and found out you either got a diamond in the rough or a lump of coal.
