HuskyDad and K9, best of luck; they will be in my prayers tonight. Animals have a truly amazing will to live, so rest assured that they will be fighting like heck to get back home to you.
And yes, they sure are worth the monetary cost. I had a cat once who developed a condition where he had crystals in his urinary tract. I gladly paid over $600 to the vet for surgery to remove the crystals. Twice. He was just a gray-and-white "barn cat," but he was also my Smokey. Friendliest, most outgoing cat I ever knew. So, Joober, I'm empathizing with you too, and you'll be in my prayers as well.
