replacement unit

[vartym]

I have a 2,200 sq ft home located in Kansas City. It's 115 yrs old. The gravity furnace was replaced with a forced air unit sometime in the last 30 years. (175k BTU in and 140k BTU out... made in 1976, no A/C)
I'm interested in high quality, but definitely considered frugal or a 'minimalist' by my friends. I've been looking at a 90% unit that could vent through the side of my house, but recently got turned on to the idea of a heat pump.

Aside from purchase price, what pros and cons should I consider in deciding between a gas fueled unit and a heat pump? (What about a ground-source heat pump or duel heat pump/gas?)

Thanks for the help!
