go for leds man you're asking about outdated technology. I hated using CFLs, the look, the space they take up, the inefficiency for aquarium purposes because of restrike, the heat and the endless replacements.
A diy led project could cost less in the long run because you'll be replacing those bulbs alot. leds last years and for that size tank you could probly do it for about 200 dollars.
