So many options. HLG has some good options for boards or the QB96's are nice too, and are US based. Or you can do strips. Building it yourself will be cheapest. There's China too, but I don't like ordering off Alibaba, and I try to buy American when I can.
I never buy refurbished shit, but I would seriously consider buying the HLG ones. 10% too with the RIU10 code.
