I've heard these machines can whip up everything from soup to nuts, including ice cream.  I've just never found them attractive enough to keep on the counter, have been skeptical about their build quality, and would never in a million years pay full price for one.   I also prefer glass carafes over plastic.

It seems like you found a good one, and congratulations on your successful return trip.  I agree that the second carafe and lid should have been included in the package, but unless they were all donated in their own box or otherwise kept together, separation was bound to happen.  About the only things I ever see sold in sets at thrift stores are dishware pieces.
