I will add that they are more than willing to assist when the none expert has a question about an item. My 2d purchase in the last month. 1st needed help with cable/interface for Heil headset to Icom 706, called and received excellent advice, 2d purchase was this week of NANOVNAH4 10kHZ-1.5GHz Antenna analyzer 4" TOUCHSCREEN which I ordered online. One of the best things about R&L is shipping as I am in North Pole, Alaska, they go out of their way to ship as fast as possible at the most economical price for the buyer. Both items received within 4-5 days via USPS using flat rate postage. As others have stated they also as a general rule have a much better price on the item. This added to shipping cost, customer service puts them at the top of the list as a for number 1 to deal with.
