So, I see all of these different types of AK's out there, but I don't know what is a good kind. I pondered an AK awhile ago, but things have been sped up now. So, what is a good kind? I'm looking for something to plink and defend with. Romanian, yugo, etc.? How much should one cost. Any types to avoid? Is there a benefit of an SKS over AK? Like I said, really new to all of this as I have not invested a lot of research yet, but need to know what to look for. Thanks.
