Funny you should bring this up today - I've literally just been checking over my trusty blackfellow and the area of corrosion around the front leg mount is giving cause for concern....the front leg is now getting rather too wobbly for comfort.
The 'One-Touch Silver' looks fine, but the 'One-Touch Gold' also has that neat ash-collector jobber. 18.5" (47 eurocentimeters) Silver seems to be about £100 (around 3 times what I paid in the USofA about 21 years ago), but I've found a good price for the Gold - must check whether it includes delivery though. What is the 'hinged cooking grate' like - is it any good or is it a solution to a non-existent question.
