If no one in the club has a 40bre. for sale, then look at Michiganreefers.cXM. They always have stuff for sale cheaper that you are going to find on this forums main sell page.
As for the lights, premium has their Ice Cap retros on sale right now, and if nothing else, I have read some threads either on MIreefers or ReefBuzz about people getting cheap fixtures on ebay that they like.
