I think my old one was a Trane, worked well I guess. No major issues in the 8 years I was there, and it is now 13 years old.
My new one is an Armstrong Air, never heard of it but it seems to work well, it's only a few years old though. It's 95%+ efficient
FWIW to the comment that people may not look at it when you sell the house, I can honestly say that was one of the things I checked on every furnace was the efficiency. I felt A new furnace that was only an 80% told me they did stuff in the cheap.
