T5 Light Fixture Debate

have any of you used the QUANTUM T5 BADBOY fluorescent grow lights or the HYDROFARM T5 4FT fluorescent grow lights? i am trying to decide between the two. the hydrofarm is cheaper by $20 and has a 5 year warranty. the quantum badboy really just seems like it is a new design. i cant find any kind of warranty for it and the only thing i see it having over the hydrofarm is the vented ballasts and reflectors. but i dont even know if those would really make a big difference. and i know that the badboy can be folded up but that is not really a plus or minus for me.

i guess what i am trying to get at is, do any of you use these or could you tell me more about them to help me make up my mind?

20$ difference i might go for the better one. i bought my fixture in CL and its an aquarium light but its got built in fans 4ft 6 bulb 90$ w/ newer bulbs
