Earlier today, just before starting a run (the Taber CornFest run, to be specific), we discovered the jogging stroller wheel was basically flat, despite being filled up the day before. This necessitated a quick trip over to a gas station pay an exuberant amount to fill it up. This got me thinking - I really should get a 12 v compressor for at least one of our vehicles. Are there any reasonably priced ones that are of decent quality?

It doesn’t need to be something completely hardcore like the overland guys use, but something that I can keep in the van/car in case I need it.  Are there particular things to look out for when buying a 12 v compressor?
