I am looking to build a garage not larger than 26x28 why would I want trusses? They are more expensive than conventional rafters?

Up to about 24' you can rafter with common boards cheaper. Usually. There are no $35 trusses around here unless they are for a mower shed. After that, trusses can be a cheaper and certainly quicker method. However, some of the savings will be eaten up by equipment rental to install the trusses. That depends on the weight, wall height and other things.
Trusses are for 'carpenters' that don't know how to cut a roof.
Really? Show me how to cut rafters for my 36 x 48 pole barn that gives me a complete clear span underneath with no poles or beams.
It's right in the span tables.

36' wide building will have a rafter span of less than 18' (36/2-wall width)
So A 2x10 16" oc or 2x12 24 oc will do it (Doug fir or hem-for, #1)
You'll need collar ties in the lower third of the rafters, 36' wide building will result in about a 28-30 tie, depending on roof pitch. Looks like a 2x10 or 12 will support the ceiling. My lumber yard stocks lumber up to 32', available with a 1 day notice. Something many people aren't aware of. And a 32' 2x10 costs about the same as 2 16 footers.
So there you have it, clear span and a higher ceiling height than if you used standard trusses. Two carpenters could frame it in a day and have it sheathed (mostly)
Falcon67, what does a 24' truss cost in your area? They are $39.99 here in Pa.
