Time does zip by. I'm still using that cheap inflator (post #9) 5 years later. It has been handy for inflating bike tires and the van air bags. I do carry a better compressor for inflating tires though. It is easier and quicker to use the small inflator for the bikes.
I'd add a tire plug tool kit as item worth bringing along. It's a good temporary fix. I've had to use my kit once. Make sure that the tool is strong as it takes a fair bit of effort to get the plug inserted. A cheap tool would probably end up bending.
