If your willing to spend a half a day building and wiring, buying a frame which takes away from your flexibility to save 150 bucks then I say go for it. 20% is also going to support the forum we all lovee and spend plenty of time in.Both options are great, but not cheap. Get some COBs and heatsinks from different sellers (ebay, amazon, cobkits, timbergrowlights etc.) and wire them. You'll save some cash.
