Sorry did not read every post. Is money a concern? I bought the new ATI Powermodule LED with T5's built in to a single unit and LOVE it. Below is a link that describes it.

With that said if money is a concern I would go MH if heat is not an issue. I have run MH for a few years and have run LED for a couple of years and if those 2 are the only choice go MH. Get a nice reflector with a Radium bulb and you are set.
