If you need such a big fridge/freezer, then buy what you can afford.
My concern is, in 15 years time, when maybe one of your black stainless steel appliances no longer works, will the black appliances still be available to buy? If you can only get stainless steel, then would you replace all your appliances, so they match?
For added info, read the article. Pros and cons are interesting.

Is this one out of your price range. Appliances on line.

You don't necessarily need an integrated fridge, have a look at integration kits that adapt to different refrigerators,

Thank you for that link, @dreamer. That is one we had seen and it's on our list of options.

@papercourtyard, I've never heard of integration kits. Are they sturdy and do they look good? I'm off to google them now.
