Hello Jeff, I do agree that the format is already the right one and that a simple, neat classification of the watch conditions (4 levels as you suggest)would be the only changes to the table format.
I am 100% with you also as for the idea of 'expanding' the list: here I think we might be a little bolder even.
Since there are a few regulars here why not try to cover a greater number of models? The current list is a descending one in terms of value, but of course a lot of the commoner models out there may not ever make it. So I thought that, at least for those models where the market is or has been deep enough, providing a estimate even if the value is low can be of great help.
It could be a simpler form than for the ABC segments, say one median value only as we have now for the current version.
Still all those Viceroys, Pasadenas, 510.50x etc. would then be assigned a ballpark value to help the neophyte or anyway the one not so expert on that particular model line. Certainly a line would have to be drawn somewhere, but it would be easy: e.g. include all the ones that have been officially given pictures in the OdT gallery (save the 'very early' ones of 1930's etc.)
Of course this would mean a much greater effort, but as a group this effort could be split among different people: I would be more than happy to help, for one. And I am sure most of us would, as we already do when a spot quotation is requested.
Just an idea, of course, my 2c.
Cheers.
