Central heating options

[Dave Rav]

Well, I just got a bit of news all of us just love - the HVAC needs to be replaced!  At least the heat component needs to be replaced (AC works).  Contractor says heat exchanger is cracked and induce draft motor has failed.  They are quoting me in excess of $3k to replace just the heater components of the unit.  I already know I won't agree to that!

I'm starting to look at other options.  

My question to the group:  

1) Besides space heaters, what other options are out there?  

2)  Has anyone installed baseboard heating in a unit 1200 sf in size?  Cost?

Thanks!
