Hi Irving, glad to here that you are getting there now with your house mods, and that you have moved back in. Are you at home full time now? I know what you mean about cost overun and snagging lists - I bet you are well on top of the latter, and that the builder will love you for it!!! You are dead right about the cost of door openers, we are looking into something similar for driveway gates, but it will probably be a non starter because of the costs. As you say, not rocket science, but astronomical prices. Anyway good luck with your new life at home - the new workshop will come I am sure. G.
