Well, it's an interesting question. Is there a market for a $300 sprinkler controller? Rain Bird doesn't think so. I paid about $50 for my controller, and it's relatively easy to use, certainly better than the OPs: http://www.amazon.com/gp/product/B003LY4I14/ref=wms_ohs_prod...

Also, the OP is eliding over the fact that that controller is probably 10 years old.
