Check out the Elkay Avado line.

Kraus sinks. 16 gauge (i.e. thicker SS than most of Elkay's sinks which are 18 gauge), and come with free grid, which usually costs from $80 to $130 extra. Do a search on this forum and you will find happy Kraus sink owners. Kraus has a 30" size #KHU100-30, and a 32" size #KHU100-32.

Karran makes great sinks. I don't know if they have what you're looking for or not.

Actually the Elkay Avado undermount is 16 gauge. It's about $1,600.

We have two Elkays in our new kitchen and they were not that much. I can't wait to use them!

Good luck!

thanks for the advice. looks like the elkay avado has a 15mm radius, as do some vigo sinks. the kraus looks like it may have slightly more of a radius. the ticor is beautiful but i can't find a non apron front.

We ordered the Kraus sink on Amazon. It arrived in 2 days! We ADORE it! The price was great too.

I second (or third?) the Kraus suggestion. We found one on Overstock.com for pretty cheap.

I purchased a Kraus sink on amazon also. Love it.

Yamsicle,
Where did you find the measurement of the corners on the Kohler sink? I'm not seeing it in the specifications.
Thanks!

On the Kohler page. I've cut and paste from the page (link below).

The KOHLER Strive undermount sink is available in five configurations; each with accessories included, and features 10-millimeter corner radii for easy cleaning and nine-inch basin depth for soaking and cleaning large cookware. As an installation benefit, the 10-millimeter radii allow for easier counter cutting in comparison to sharper corner radii. The Strive family of sinks is constructed of 16 gauge stainless steel, a thicker, more durable gauge than many others at this price point.

Love my ten inch deep Kraus 30 wide from Overstock 3.5 years-ago.

I'm also a Kraus owner. Bought mine on Build.com. The slab guy thought it was a $1200 sink.
