Finally got the one from Willimas-Sonoma. Made very, very quick work of chopping an onion for Chicken Parm last night. Two whacks -- one for each half of the onion, and I had very nicely chopped onion. Big, BIG time-saver, and this on isn't all that expensive. Comes completely apart for dishwasher cleaning.

Good - no more crying or "pound pound pound" on the conventional chopper.
