I've ordered from them in the past. They're a husband and wife team and they get their guns from India. My experience with their customer service was very good. They're not always there to answer the phone, but if you leave a message they get back to you quickly.
As far as the Brown Bess musket I ordered from them, I got it for 60% of the price that a Pedersoli would have cost me. Unfortunately, the gun itself needed some work to get it to where I was happy with it.
At this point, I've refinished the stock, reworked the trigger, dulled the finish on the barrel, (they come so highly polished that they look like they're chrome plated), "adjusted" the barrel until it shot to point of aim and tempered the ramrod.
Now it looks and shoots pretty good.
I've had a blast shooting it, but in retrospect I feel I paid too much for it. It really shouldn't have cost more than $400 IMO and I have seen them used for less than that.
