If you're not into the glitter lines that MHs make, ATI 6xT5HO Powermodul is pretty sweet. You can mix and match bulbs to get the color you want.
My friend has one that he's going to put into his AG Mission canopy whenever it comes in. The reason he's going T5 is that he likes the look of the canopy and it's not too tall looking compared to other DIY canopies that have MH's and it matches the darker red wood furnishings in his living room. IMHO, it's all about the overall look of the set-up that you are going for.
