Has anyone used Amvona's daylight-balanced 6-tube flourescent lightbanks?

Amvona couldn't supply another product I recently ordered, and now they're offering me a pretty big discount on a pair of these.

Any comments on build quality and usability would be welcome. Thanks!!

The only way I'd buy that is if I charged it to an Amex card to add another year to the warranty.
