I've been thinking of looking into trading my 30-06 for an SKS. Not 100% sure yet though. I collect the 7.62x39 for my AK and figure it'd be good to have another decent rifle that shoots the same rounds. Are they a reliable rifle? Any makes to look for, or look out for? I don't know very much about them obviously. When you do the conversion to extended magazine does it negatively effect them at all?
