This is a great, authentic, old-school camera store. Allen's camera offers a wide variety of film, camera and frames with a pretty wide range of prices. But... like so many other places, you get what you pay for. The expensive stuff is great, the cheaper stuff is... cheap.
As for photo work, their lab is really good and they can give you exactly the quality their looking for. For the most part, the staff is both qualified and knowledgeable to help you with your photography needs. They're also friendly and helpful.
And about as expensive as most good quality photo places.
