Actually, I just found it cheaper ($69.53 w/free ship) at amazon: Amazon.com: Slime Powerspair - 48 Piece Kit Tire Repair Kit: Automotive

Don't mind the extra size as I will have the storage compartment - where my spare should be!!!

Peng, for some reason that link works but with no images. I think I have seen the spectrum (unless you are saying the "largest" one is larger still than the 70004). Unless I see something else that grabs me more, I'm headed to amazon. BTW, Northern has a pretty low score on resellerratings: Northern Tool + Equipment Catalog Co. - northerntool.com - Reviews, Ratings and Prices at ResellerRatings

EDIT: another reason I'm leaning towards the larger compressor is the larger tires we have and the inflate time. Of course, i would be thrilled to pay for this and never have to use it!!
