I'm in the process of doing my first import with them (3 rifles and a handgun). I'm at abotu the 7 weeks point of waiting, which is not unusual. So far it's been a good process.
My only real "complaint", if you can call it that, is that until they call you, i's really not clear how much money you need to have set aside to complete the importation. Their fee is clear, but it's a total mystery what duty, tax and shipping may cost.
I will say that I MUCH prefer PR (so far) to Questar.
