Hair dye: Whats the best brand of 'funky colored' dye?

I recently used SFX Iguana green after bleaching my hair. I don't care much of the Iguana green. I had it about a year, so it didn't stick too well to my hair. What brand would you recommend for 'funky' colors that I want to put in my hair? I know theres SFX, and Manic Panic (Which I don't really care much for.. I had my hair pink last year, it didn't last long.) So... whats your reccomendation?
