www.portablegaragedepot.com for $2,199.00 (round style roof with heavy duty material) + s/h and any options such as 2 vents, easy roll up doors. The heavier 12/14.5oz material is suppose to last 20 years. These come in tan and grey I believe. As far as snow load goes I think there is a disclaimer on the site that says only an engineered structure is guaranteed to withstand snow loads. Warning, I just found out I probably will need a permit from the city to erect it. Still researching so check your city code before you buy.
