Fixing vs. Buying a New Engine / 273

I woudl say it depends on why the cylinder is low. A leak down test would tell you if it was rings, or a valve. Rings are expensive to address, a valve isn't. So assuming it's a valve, I'd go with Hebrews - buy Mad's 340 (he's a decent guy too - so you might be able to deal) and then determine what's wrong with yours a little further than saying one hole is weak.
