Can't you have them plumb for the SWG and then buy it yourself and install it? It will probably be cheaper to get on-line? We paid $1200 for ours with the pool - I hear other people getting it for closer to $800 here on the forum.

It depends on the BBQ - are they running gas line to it? It might be better to have them run the gas line, but then you install the pit yourself - you might save enough money for both.

Or you can do what DH and I did - we are looking at adding the Aqua logic system - figured it will cost $500 plus removing the child fence and installing alarms on the doors/windows. $500=10 times eating out = eating at home for the next two months.
