Here is a low divide Kohler I installed for a customer.

A low divide from Urban Place.

We have the 60/40 low divide Crosstown undermount from Elkay and love it! The corners aren't to sharp, so it's easier to clean, and the 60/40 gives me a large basin for washing and a small one for either prep or draining. It's a Build.com and Ferguson.com only model. Elkay also does 50/50 low divide and has it in some apron-front models as well.
