I am a full-time professional photographer who has used Arlington camera for over two decades. I make a 30 minute drive past several other camera stores to shop at Arlington Camera. Bill and his staff are the best!
They buy your old gear, they sell new and used equipment They let you try most products before you buy. Try that with B&H, Amazon, etc. They also have a very knowledgeable staff, with decades of photo experience. Try to get that kind of knowledge at your Wal-mart, or Best Buy. After you purchase something, you can always come back and they will help you with any issues you have. Try that with your on-line, out of state purchase. Also, their inventory is incredible. Digital/film, stills/video/audio, Software/hardware, educational videos and books. Rental equipment as well. Are they perfect? No. But I've never heard of a complaint that wasn't resolved in a favorable way.
Arlington Camera also has competitive prices.
Bill is also the best supporter of the local photographic community. Ask any full-time pro. Arlington Camera is a photographer's candy store.
Another great thing about Arlington Camera is that their sales staff are not on commission. At least I don't think they are. I've never felt any hard-sell, or have them twist my arm toward an off brand product like some camera stores.
When I saw the unfavorable comments here, I was shocked. I'm also not so sure that they were actual customers. A competitor maybe?
BTW, I know Arl. Camera ships products out of state on a regular basis.
