a place that will sell you a 95% efficient 96K BTU furnace for $1363 - $1433 (depending on desired fan size). They also sell furnaces that are 93% efficient, but the 93% models would only cost $100 less, so you'd be better off with the 95% efficient and the tax breaks.
Based on this, I don't know why your salesman wants to charge so much more for the 95% efficient model. Also, did he explain about the ducting changes that would be required for a high efficiency unit? If your ducts are sufficient to carry the higher flow rate of a single-speed fan, it's not obvious to me why they would not work to carry the (generally) lower sustained output of either a variable speed fan or a multi-speed fan.
The Goodman brand (sold at the link above and at other places) is a perfectly fine furnace, the warranty on the heat exchanger is among the best in the industry. The brand is one of the largest manufacturers of furnaces and AC units in the US, but they sell primarily to institutions and contractors, not through retail. They don't pay for advertising. Do some research on the web, I think you can satisfy yourself that they make good equipment.
I bought my furnace from these folks, it was not a problem. The problem may be finding a good HVAC guy that will install it for you. Maybe look for an HVAC guy who wants to take on a side job and will sign off on the warranty card. You could save a lot of money.
