I've actually started looking for a 172 with a blown engine to start the process over again.

I wish you two things for christmas:
1) The exact run-out airplane you're looking for

2) And a smooth and easy transaction with the buyer of your super nice 150
I did exactly what you did, refurbished completely my 150/150 and if I had to do it, I would do it again and change nothing.
Let us know when you find the rare bird.
