Any comments or suggestions as to which course of action is better?

I've always felt that repairing my cylinder was the way to go, but I'm not sure
I'm right. I had to do one of the cylinders in my old 150 twice in less than two
hundred hours time. I've just always felt uneasy about swapping mine for someone
else's repair job.

These days I might opt for new from an outfit like Superior.
