I recently transferred a gun through Verona Gun Safe that I won on gunbroker. They only charged $25, which is quite a bit cheaper than other shops in the area. The staff was friendly and courteous - I spoke with Tony, one of the owners. Most importantly, they were willing to work with me as I am not a US citizen. Many other shops that I called flat out refused to deal with the extra effort of transferring a firearm to a green card holder. I was surprised to see silencers for sale, but Tony assured me that they are legal to own.
