Have you checked on EBay? Sometimes they have things when no one else seems to....good luck.

Another possibility is to trim the cabinets to fit the sink. I thought about doing this so I didn't have to have such a big sink cab.

This Kraus sink is on sale for $333. There are a couple of places on Amazon where you might be able to get it for less. The expressdecor.com site shows that it fits a 33" cabinet.

I'll see if I can find anything else for you.

Here is another one that might work for you, and it is $225 on Amazon.

With your smaller size, what you don't want is a double bowl. That's two too small bowls. You'd have a MUCh ore functional setup with a single bowl, or a 75/25 configuration. That way, you can at least have one bowl that you can fit a large pan into.

Ditto what Green Designs said: The bowls will be too small.

We ended up getting a sink from a place called Gemini Sinks (http://www.geminisink.com) We got the exact same size sink we currently have (13 3/4" x 16" x 8" bowls) for $349 including the drains. Thanks so much for all your suggestions. I feel better I have one in hand as our templating is scheduled for two weeks from now and I was going to worry the whole time about shipping if I had to order online.

I haven't had any trouble with this size in the past (actually I never noticed they were smaller than anyone else's sinks).
