I'm not sure if there is one near you, but there is a store called Diver's Direct where I bought all of my equipment. They have everything and great prices. You may want to take a look. I know they have a catalogue and a website.
On another note - I don't know if you'll be missing anything diving in cold water. I have no interest in it. The springs in FL are too cold for me and they are a constant 70 degrees. I guess I truely am a Florida girl
