Hey DVD,
I have both the SKS and the mini-30. To tell you the truth I don't shoot either of them that much. I mostly take out the AKs, but if I had to choose between the two I would take the SKS. I don't shoot mine much because it is russian and in pretty good shape. They have romanian ones at Traders in San Leandro for 189 all the time. I keep thinking about getting one but most I have seen up close are pretty rough.
I am definitely going to get one of the Yugo ones when they come out. They are (supposedly) in excellend condition with bayonet and grenade launcher on the barrel. This should get by SB23 cause it has a ten round fixed magazine. They are supposedly gonna sell in the 300 dollar range though.
The mini-30 is an OK rifle, I really don't have any complaints about it, it just doesn't interest me enough to take it out and shoot it.
Good luck with whatever you choose.
