Recommendation for forced air gas furnace

I'm looking to replace my old natural gas furnance with a unit that has the following featues:
- Natural gas furnace with variable speed motor; - Energy Star (mid- to high-efficiency) unit; - Needs to heat older house that is about 2600 square feet in size; - Average winter temperature outside is 30 - 35 degress F, rarely goes down below +10 degrees F; - reasonably reliable and cost effective.
All recommendations appreciated.

This is Turtle.
get a furnace with a 90%+afue rating , Veriable speed Blower , and get a heat load run on your home to see exactly what heat load needed to heat your home properly.
Not to pick the brand out of the bunch of manufactor out there.
Find a Good Respectiable hvac installer company , have the heat load run on the house, Get exactly what the calculation says to get , and have the GOOD RESPECTIABLE HVAC CONTRACTOR INSTALL IT. The only thing that really matters here is it is installed correctly and meets all the spec.s above here.
OH, The Brand , Any brand that a good respectiable hvac contractor will sell. Years ago brand was thought of as good better or best. Now days all manufactor sell trash models and the good stuff. A Good hvac contractor will explain the difference if you just ask him. Good hvac installers don't sell trash for they can get a bad name by selling trash equipment.
Another note here. if any hvac contractor does not run a heat load calculations on the home and does not go by them. Run his ass off. This is the deviding line between HACKS and Professionals.

Turtles reply is the same as mine. You dont go looking at the name on the unit, you look to see what the professional that properly sizes the unit is installing.. The poster that suggested Maytag had good intentions, however his warranty information was wrong, and as an example, you can get cheaper units with a lifetime exchanger warranty, and 10 years warranty... The warranty is really not an issue, but the service that you recieve is.

Look at the warranty, Maytag its great, I know CBHav is saying about service, the guys that installed mine could not do enough to please us, the guy even called on a Saturday @ 7:00 PM just to see how things were going, and if I had any further questions.
Check with your Better Business Bureau......... here's a link to HVAC, read some of the comments. There all there Trane Lenox ,Coleman.
