My gas wasn't cheap...
Think it was about £180 to buy the bottle outright (which includes a built in regulator).
Refills/exchanges are then around £38 a pop.
You need to start a thread soon CTWV50, it'd be good to compare notes
Haven't done anything on the build for the last couple of weeks, been busy with far less interesting things.
Made a start stripping the donor at the weekend though, and already sold a couple of hundred quids worth of stuff on ebay and mx5nutz. I've got high hopes of breaking even on it!
