Harry, I think what you're looking for is usually called a "clearo" or "clearomizer" and almost all vendors sell them. There are many different kinds of clearos though, and your description could fit any of them. Do you know which kind it is that you like?
You can try looking at GotVapes since they have several different kinds:
GotVapes.com, E-cigarette Supplies - Atomizers Cartomizers Mods Juice and more
Also, when you say "fit standard batts" that could mean several things. I'm guessing that you mean one of the thin, smaller
batteries that most of us started out using, the ones that look more like an analog? You need to know what kind of threads your batteries have if you want to get the right clearo. You probably need 510 or 808 threads, but you'll need to check or provide us more info to be sure.
As for a 1300, check out the "military" battery from The Vapor Girl:
The Vapor Girl: Electronic Cigarette Kits, E Cig Mods, E Cigarette Liquids & More Those come with either 510 or 808 threads. She also sells some clearos.
