C&H and Keeton are great machines, but don't limit your purchase to what you have used in the past. There are good 48" Fletcher and C&H cutters for sale in this section of the forum. I would buy a Fletcher 2100 or 2200 before I would buy an antique C&H 40. I'd also look at the C&H 40Pro's. Those are great machines too. And you'll be able to learn to use either newer model really quickly. Easier than using the old C&H40, and easier to get a replacement part for the new ones, if god forbid the highly unlikely ever happens and you need a new part. (Only can think of the wooden base getting wet and warped, Fletcher's have a metal base)
