checked up on him too since i am in his area...he is def. not trying to turn a profit, just had some problems w his lease and is trying to sell his 15 bucket system. I think the reason he mentioned that any size setups were possible is because people might be interested in say a 5 bucket system etc. Seemed very reasonable when i talked to him and explained his situation. Hes got a 15 bucket system,the fill/drain holes pre-drilled w fittings, 15 netpots, a 300 gal res, all fill/drain tubing, the drip system complete, and some various other gear that could be used w the system. He is not selling his AC or Chiller but i previously posted a link to the most affordable chiller i could find in CA, check it. Seems like he would be very reasonable if someone was interested...wish i had seen this before i set up my 18/17 system. Prob would have saved me alot of running around!
