We have whirlpool gold series appliances.. all 4 are stainless and black. I love them. They're actually stainless, unlike Frigidaire for example which aren't really stainless. If a 'stainless' fridge is magnetic, its not real stainless steel.

I think white appliances look dated, and tend to look dirtier than black ones. If you plan on moving soon, and plan on leaving the fridge behind, I'd try to match the other appliances. It looks better when they do all match. Also, with a smaller kitchen, black appliances might be better because they wont look so big and overbearing compared to everything else.
