Honestly replacement engines are getting pretty cheap nowadays, you can find one with 60k for around $1000 bucks and swap it over in a weekend. I did that when my old 04 developed a rod knock. That way you will not be spending a bunch of time and money on an engine with 300k miles on it
I agree however Im in Canada, everything here is almost double the price and thats if you find anything. It really sucks the big one.
