We have been more than two months a Weber Q140 and recently came to the point that we (the first was supplied with grills included) times our aluminum drip tray discard and replace with a new one. Out of interest I've just ordered the original accessories. However, I was at our local distributors for those trays (disposable tableware - trays) and also bought interested the smallest size.
Conclusion: I got 40 pieces more for the same price of the original - and this version also fits perfectly.
