I'm not far from you (central Bucks). In our climate, factoring in all things (like expected future elec rate hikes, very unknown future fossil fuel prices etc) my opinion is a heat pump with fossil fuel back up on 1st floor is optimum. Regarding 2nd floor, typically I'll go heat pump with elec back up....since some of your 1st floor heat will make it's way upstairs, the 2nd floor back up (assuming good attic insulation etc) should require relatively little useage. Note also, this approach serves to diversify your energy demands. In some years it may prove imperfect, in years of $4+/gal oil, you'll be thankful.
Also, as you noted, the best bang for the buck is KEEPING the conditioned air (either heated or cooled) that you pay to make. That means proper air sealing/insulation, etc etc. I've seen (and fixed) attic insulation that was insufficient in quality and/or quantity.
Check my profile for my email if you want to discuss this further.
I meant that I didn't know any that worked...

Yo! here in PECO land HYBRID HEAT is a MUST!!!!! You either have to do both with heat pumps or go with 1 large system,since the heat pumps must serve over 80% of the home to get the LOWER rate.I may have a GOOD contractor up there that can help you out.See my email in my link.
It's NOT the BRAND,it's the company that installs it!!!!!
