Here's the GM set for ~ $900 (priced as each):

These have the inner groove on the edge of the square lip and are 3.25" deep. It still doesn't look to have a stepped lip, although they describe it as such.

Those ones below from ineedahupcap.com are advertised as 3" deep and shown with the stepped edge, but that's not what they sent me. This is the third set I bought (from various vendors) and didn't get what's in the picture! I'm refusing to pay return shipping this time, and waiting for their reply.
