Definitely an interesting variant to collect and with all the different DP+( city code)....easy to rationalize collecting
Also they will have the "bulbous" style gas block so....another reason you "just have to have 1"
Most do seem to be on the rushed/lower end of the 1's I've handled and seen but I lucked out on my DP as it's on the high end of build quality. A lot of cast parts but finished well.
If the price is right, I say go for it
Then again....If your looking to be talked out of a SKS purchase....well...
