If I were you, any new appliances bought would be stainless, but I would keep the fridge if you like it and it's still working. When you sell the house, the new owners will probably replace it. Which means you might be able to take it with you when you left.
FWIW I got a 'stainless look' Whirlpool refrigerator that we really like and it was not $2k. More like $1200. The other great thing about it was that since it wasn't actually stainless, magnets work on it.
This is a similar refrigerator to ours.
