I just recently picked up a Sub2K, and it's quite nice. It does not seem as high a quality as the RFB or KSG, and there are a number of sharp edges that needed to be broken down a bit, but after that it was good to go. It reminds me a lot of the MP5 when I dump the bolt from a locked open position to battery. Out of the box, with the less than stellar sights, we were making 3" groups at 25 meters. In terms of accessories - I know there are some available, but in reality, I like the plain simplicity of the gun as it sits. It folds easily, can be locked in the folded position for storage and fits very easily into my pack. Yes it's more expensive here than in the US, especially if you buy one of the EE, but I was more than comfortable with the retail price I paid from Lanz Shooting Supplies (God bless you Seth - rest well).
