Good luck on your search!
I scoured craigslist for several months and finally got an HX that consumed oil.
It's better than it was, I think, but it has its issues.
My wife's '96 Accord DX runs like a top but only gets 29-30 mpg.
Civic DX came without a tach but apparently it's not too hard to put one in.
Probably the same with the Civic CX.
Just FYI.
