I've use the   (You need to Login or Register sinks for several years now (so long in fact that this year I'll be using new ones to the place ones that are beginning to show their age).  I like the "hold open" design ... stays open by water pressure when filled.

I actually use 2 ... one for washing and another for rinsing (marked so they are always used for the same purpose).  The rinse model is also used for bathing and for collecting water.
