Let me just throw a spanner in the works and offer an alternative to the Weber. 20% off at Barecues Galore at the mo.

The one to look at as a comparison to the middle Weber would be the twin grill Ziggy. We've got the smallest one equivalent to the BabyQ, can cook properly with lid up or down. Use it as a stove, i.e. boil wqter, use saucepans with use of a trivet. So can grill on one side whilst boiling veggies or whatever on the other. Nice bit of kit and well made.
