Most of mine are Generation and mostly ok. I have a 'C' which is a fave of mine and is pretty old now. I did buy a new one but have always gone back to my original one as i find it's mellower (if that's poss).

I also have an irish 'D' (with the green plastic top) - sorry can't remember name and the label's rubbed off yonks ago - which i find brill to use.

There seems to be loads on the market including American makes and some very expensive.
