Single-zone vs. Dual-zone fridge

[Erik Kaffehr]

I'm considering picking up a fridge and noticed the price increase if you get a dual zone. Which I THINK will be nice to have. But I'm wondering if I'll use the freezer portion to justify the expense. Then I was thinking if I go with a dual zone, these need to be larger for obvious reasons. Taking up valuable space in my rig.

So, those that have considered a dual zone fridge or even have one, do you use it enough to justify the extra cost?
