What spare parts should I have for a Coleman DGAA?

[archive]

I have a Coleman DGAA056BDTA which was installed last winter. In your experience is this a good reliable furnace? Which spare parts, if any, would you recommend for this model that seem to need replacement the most often?

Last winter the pressure switch died and we were cold for 4 days until it came in the mail. If possible I would like to have a few parts handy that are most likely to wear out. Thanks.
