Need a computer, audio, data, or video cable? Need any of those obscure parts to repair something electronic? This is the place, especially now that Radio Shack is going away. Almost always better prices than Best Buy on cables and cords. The store is hidden away in the industrial part of Beltsville on the east side of the RR tracks. You have to make a left turn at the bottom of the bridge, which immediately turns left, then follow the road to a stop sign and turn right so that you are going north parallel to the tracks and US1. It’s on the right about 200 feet after that. Always friendly and interested service — if it’s not in the showroom or the large inventory in the back they will be glad to order it for you. If there’s a soldering iron in your toolbox or you’ve opened the case on your computer you need to know about Mark Electronics.
