Hey CA, if I were you I would buy 1 good panel from A51/BonsaiHero/Apache, then keep adding more as you make your money back. If that's not feasible, learn the DIY route. Chinese panels are a huge crapshoot but I think some people would agree that this company builds good units. And they take PayPal.

Otherwise maybe get 2 BonsaiHero panels (500 shipped) and just keep adding CREE bulbs. Good Luck.
