No experience with model 1, but I've had an order in with DSA since Oct. 15th (yes, FIVE months ago), still no ETA. Good quality products, but mediocre CS and abysmal shipping times. The initial estimate was 3-4 weeks, and ever since then it's been "by the end of (insert current month)". I figure I might have it by 2014. In the mean time, as soon as NFA stamp gets my stamp back to me, I have to send in a letter amending it from the 11" description when I ordered the DSA upper to either 7.5" or 12.5" for one of the uppers I acquired locally in the weeks following when I got impatient with DSA.
If you don't mind the wait, as I said, their quality is excellent and pricing is very fair. I really like my DSA FAL para carbine, too.
