Stretch the budget to $450 and get an OR-IT2081 or a Photon32. But if that's a big issue, and/or you don't care about sunrise/sunset (it's certainly not necessary) then look at any fixture sold by somebody you can contact. Like somebody who has a sponsor forum here on RC. Or at the very least has their own website. Buying an unknown brand from Ebay or Amazon that doesn't have a website with customer feedback in a forum, is a real crap shoot. How good are the fans (noisy), the heatsink (does it even have one), the case material (steel... rust issues vs aluminum) and case finish (paint vs powder coating).
