Many thanks for all the replies and advice. I'll be going for a new easel sometime this summer but, very regretfully, it's been put on hold for a little while as I apparently need a new fence more than I need a new easel! :-(

I'll probably be going the new route and probably for either a Beard or a Dunco, as Saunders are like rocking-horse droppings on this side of the pond. Of the two a Beard is most likely, provided I can talk Calumet down on price by a good old chunk.

Again, thanks for all your help!
