Someone on another forum (non-paddling) is looking to buy a cheap and
stable recreational kayak to use as a platform for photography on
sheltered water. He lives in Manassas, VA. Can anyone recommend stores
in that area where he might be able to rent some different types to help
him decide before buying?

I would recommend Atlantic Kayak.
