It's actually a tough call - do you have the space to do a 24" dedicated to wine and a separate 24" dedicated to refrigeration? If so, I'd actually recommend that. The drawback here is going to be the cost - the Danby (and from what I see of the Kalamera here) are both more or less going to be considered the low end on these units. You can definitely find dorm style refrigerators for way less, but those can't be built-in, you need something that breathes out the front and those tend to be designed differently.
When you get to the mid-to-upper end undercounter units, they're made for building in and also tend to be more than just a "cold plate" appliance - usually with a strong compressor to aid in keeping the temp down after being opened, convection air circulation, and better humidity control (especially important for wine). Price-wise though you're jumping into the $2000-$4000 range per unit. The only other brand I know that does a split style unit is U-Line, and it is a bigger unit at 36"W, but you're pushing yourself up past the $4K range at that point:

As for other options, pretty much everybody else does the 1-2 racks on the top or bottom for wine that I mentioned before. If you do two 24" models side by side though, the Whirlpool brand can get you in and around a $2K price point in total for both. They don't offer an all fridge unit, but you could do two beverage centers side by side, or if you need these more for wine, one bev and one wine (especially if you tend to drink more reds or whites, it can help you split them up by temperature). Either way, here's the webpage with those options:

They're called Specialty Appliance and they carry a lot of the same brands we do, located in Denver, Ft. Collins and Louisville. Here's their website:
