I purchased one from Amazon a few weeks ago. I found that it works better on my newer One-touch than it does on my old Mastertouch. The lid on the mastertouch will just slide around and not fit, but the lid on the newer one-touch will fit tightly with no movement.
Also the rotisserie ring fits tighter on the newer one-touch with a smaller air gap, compared to the mastertouch.
I had no idea that the bowls and lids had changed over the years but apparantly they had.
