Contemplating a switch to T5's

[impreza]

Hi,

I currently have a 250W MH pendant over my 28G nano cube and find that it runs a bit too hot for my liking.

I'm looking at the 24" Sunlight Supply Teklight 4-bulb unit. Anyone have experiences with this fixture? I am new to T5's and don't really know which fixture is considered to be the "best" - at a reasonable price.

Also, who carries these fixtures at the best price? (Either online or local in Calgary).

Thanks!
