overflow boxes

[outtafocus]

I have read so many threads saying the CPR overflows where no good, but it seems you guys are having really good luck with them. Im confused, Utubes or weir style?? I guess it comes down to personal opinion.

I really dont like equipment that looks unprofessional. The bear unit is very professional.
Andy do you think black acrylic or clear would be a better choice? I know the black will prevent algae growth but the clear you can always see whats going on.
