If you can find a good deal on one, by all means get one. However, I did read an account of an LGS in Texas selling an SKS for $975, and that is way too much. The other problem is in getting 7.62x39 ammo. It just isn't readily available right now, and when it does come in, it is bought up rather quickly. You almost have to be in your LGS as they stock it on the shelves, in order to get any, because it goes that fast.
If you can't find a good deal on one, I would wait until the panic dies down. They will be available for a long time, because so many were imported into the US.
