You will go crazy trying to "match" stainless steel appliances. Sometimes the stainless doesn't match even within the same brand. My advice is to get the fridge that has the features and configuration you want, and not worry about the stainless steel finish matching your Bluestar. Also, Bluestar offers painted finishes which look awesome. Have you thought about a painted finish for your range?

If you are looking for handles to match Jenn Air pro handles that come in freestanding or built-in fridges match very well.

The Viking freestanding handles also look like the BS handle. I would skip the Viking built-in.

Sub-Zero offers several handles one of them is a close match to the BS but I forget the name.

Then there is always the choice of getting a custom panel fridge and just getting the handles you want.

In addition to those mentioned, electrolux icon pro handle goes almost perfectly. One of the main reasons I purchased my icon pro is exactly because it looks so perfect with a bs. Beware tho, there have been complaints that these units can not hold their temps. I have not seen very many (if any at all) recently so the problem may have been fixed. Mine is fairly old, I think it was manufactured in '07 (08 at latest) and I have not had that problem, but I have had smaller issues to deal with.
