Ted, I have 3 also and its more than reasonable to refill them at my ace. Since I brew beer have a burner just for that so its on my ground level as I have paver's since I have a pool so I brew down there. Got a tank hooked up to the 1000 which is on the deck and 2 tanks on the ground level so when I need to brew just grab one of them. I am lucky my Ace is 5 miles away so not a great chore to get them refilled.
Since I did a Weber performer which has gas assist will probably buy the connection down the road that will hook it up to a 20 pound tank and again the performer is ground level. I get the people who have nat gas as you never run out but if you have multiple stuff you want to hook up it does not work.
Funny story or maybe not used to live in Cape Cod grilled year round and I had a nat gas grill and yes it was nice never ran out of gas. So one night in December grilled some steaks went to eat, those days I let the grill run after the cook then cleaned it which I do the reverse now wait till the next time I use it. So the wife and I had no kids in those days probably knocked down a few bottles of wine went to bed. That night it snowed about a foot, came out the next morning looking over the back yard with the snow then looked at the grill no snow, forgot to shut it off ran all night so of course it was clean.
