I'd suggest a metal project box that would double as a heatsink if you are going to box it. You shouldn't have any problems with 200ma then. FWIW, my open air installations haven't complained yet about the heat, I haven't even noticed the regulator getting warm.

We do need to wait on the autopsy report on Andrews before deciding on a course of action there. I really want to keep the final product as simple and inexpensive as possible.

Edit: I should also mention that it isn't *really* necessary to run the backlight at 200ma, I run it on its lowest setting day and night without a problem. I turned down the brightness values a bit in the sourcecode, that is far easier than changing the circuit.
