Well from all the crickets chirping around here, I would say there is very little experience with them. I haven't heard anything bad, and most of these companies are legit. Again, if you use a credit card and they don't deliver, and act like douchenozzles, just dispute it. You are given your money back and not delivering goods is a good enough reason for your card company. Then you can move on to the next vendor. Backcountry.com has 390's in stock, but they are only the s/m's. I have a hunch you are looking for the large size.
