I bought my Gaslow system from Hamilton Gas- cheaper than direct from Gaslow!! So easy to fit even drilling a hole in lower skirt. Plenty of videos on YouTube to show you and a good one from The Wrinkly Nomads fitting refillable gas and electrics and even deadlocks!Cheers, I have seen all of those, the all seem to do the same job? If thats correct I suppose it will come down to price and service.
My favourite is espresso, my machine is one of the first things on the packing list, after the dog!
