It works out cheap enough for me as I Don't have too pay rental. Though I'll have a look at boc as they have an agent in fort william and I may get bottles quicker from them than HIS.I just go direct to the BOC depot in Inversneckie, where the nice man lifts the empty bottle out of the car and loads the new one aboard for me. Easy and never had any problems, except when they gave me a bottle which wasn't full [according to my gauge. Called them and much apologies and a fresh one delivered to the door next day.
I'll have a look and see if they do locally.I have gone over to Adams gas which is local for everything except OA which I still get from BOC, seems reasonable.
