Hi, in same position as you, I would love to buy one for the collection!
Think the Biolite should work well as we bought a 2nd hand Lotus Grill BBQ about 5 years ago for £30 (and purchased a lid for last year) which works on same principle with the fan. The fan means its up to cooking temp in about 5mins which is great if we head down the beach after work in the summer for a quick SUP + BBQ after.
We use one of these for a firepit at the moment, as easy to move around when burning (with heatproof gloves!) if the wind/smoke shifts.
