Building a garage, cost $$$$

Just a warning, there are different type of kits, the ones built with steel beans are much stronger. This one is built with waht looks like hollow 2x4's, they are about as strong as a garden shed. If you live in areas of heavy wind or snow, it would not be a good idea. I would do some more research into the stregth of these kits. The price itself seems reasonable, just make sure it is sutable for your needs.

A hollow 2x4 is nearly as strong as a solid 2x4 and you would only need to go slightly larger than 2x4 to make it stronger than a solid 2x4. The only issue with hollow tubing is to ensure there is enough wall thickness to resist impacts that can cause them to buckle.

As long as you get construction drawings signed by a professional engineer in the state where you plan to construct the building it will be plenty strong to with stand snow loads and winds to a level that could be expected in your area.
