Take a look at AJ Madison or give them a call. link The site lets you filter by size. Be aware that counter depth fridges are deeper than 24", especially when you add the space needed in back for ventilation and handles in front. I believe built-ins are the only way to get true counter depth (but I'm not a pro and don't have a built in.)

For any model you get serious about, be sure to check the specifications so you know exactly the dimensions you'll need. (Look for a picture similar to below, but for your refrigerator. It's usually in the user guide or installation guide.)

Fisher & Paykel makes a 31" that meets all your criteria. Look at model no. RF170WDRUX5N

I have the F&P refrigerator mentioned above and I LOVE it. It replaced a huge 22 cf refrigerator and I swear this one holds more. I call it my "magic refrigerator". I had a terrible time finding a refrigerator that would fit in my space and allow me to open the door fully as one side is against a wall. I discovered in my search you must also be very aware of not only the handle depth but the hinges. Some hinges require more space to the wall side than others so you need to not only look at the general dimensions but at the install directions. The F&P was the only one that would fit and I had no idea that it would become my favorite refrigerator.
