Personally, I have an ARB twin under the passenger seat of the truck which I highly recommend. But it is overkill for most. Viair, has some more economical choices for occasional use. For plugs, Safety Seal makes the best I have used. I have no affiliation with these companys other than I have used lots of safety seal plugs and several friends have used and recommended viair compressors. I will also echo Chaosmagnet's sentiments on fix-a-flat, I've never had very good luck with it and would only use it as a last resort.
