Two schools of thought on this, I love my carbine, it's got some history, is as PC as a semi auto gets and I think it's a all around a better built gun than the AK but...
Even with Bush in office how long are the AK's going to be available? He has already said he has no intention of lifting the Assualt Ban when it sunsets. The carbines prices have already shot sky high while the AK's are still reasonable. Also you can gravel your driveway with the 7.62X39 ammunition it's so cheap.
If I had to put one off for now, I'd jump on the AK. It's not as good a deal as it was ten years ago but still available at a good price and when this "Private Ryan" stuff dies down in a few years the carbines will most likely still be available and may have gone down in price. If you put off the AK long you may not even be able to purchase one at a reasonable price.
Just a theory, Blue Duck
P.S. If thats your intent it may not be a bad idea to pick up a few of those cheap carbine mags now while you still can.
