Just a thought on the two different type of "slatgrills/options".
With the Arctic Fox type, you need some sort of windscreen IF you set-up somewhere besides a fire pit and the wind is an issue. IF you add a ash/snow pan, plus a windscreen, your adding extra weight/cost.
The other types have a windscreen built into design and can be oriented for maximum efficiency. With optional ash/snow pans, you could set them up anywhere.
Both have appeal, you just need to pick the one that fits your style the best and at least for me, which one allows more flexibility :-/
