Well yesterday evening we went out and looked at gas barbecues at B&Q, Makro and Focus.
B&Q had quite a range but none really attracted us and few (if any) were actually properly assembled which didn't help.
Makro only had a couple, the £249 Outback one looked OK but being up on a 'first storey' shelf it was rather difficult to get a proper idea of what it was like.
So, on the way home, we looked in at Focus and their 'Miami' gas barbecue looked pretty close to what we wanted, Four burners, reasonably solid, £199. After debating a while we bought one.
It took a fair while to assemble but was mostly straightforward apart from one slightly dubious area of the instructions. It worked first go, i.e. the gas lit and we cooked some kebabs on it to celebrate.
I'll try and remember to report again on it after we have used it for a while (if anyone is remotely interested).
One thing that felt a bit vague was the 'click on' gas regulator, presumably this is the same on all barbecues and has nothing to do with the barbecue design really so I can't put it as a negative point against the Focus barbecue in particular. It just didn't feel convincing enough to be a good, safe, gastight connection to the gas bottle though it seems to function OK. I'd be much happier with a screw on connection like I'm used to from the past.
