I was contemplating building a UDS but decided to just buy a weber Smokey mountain.
I can get the 57cm for £350 which is only £50 more than the 47cm...
Not sure if I would ever need the extra capacity of the 57cm but I guess it may come in handy one day. So really it's just the running cost that is my concern. So my question is 'Does the 57cm really use a lot more fuel over the 47cm?'
