Since I know many of you, like me, are into "affordable" items (ok, cheapskates, there I said it

There are the cheap eBay/KMart air compressor jobbies, or for similar price, manual foot pumps. Which does a better job for topping up the tyres by a few PSI? I dont need the full blown 4WD air compressors as I dont have the budget and dont intend to pump masses of air.
I have borrowed someone's cheapie air compressor and it took a long time to even get 2 PSI in! I dont mind the manual labour (and saving my ear drums) if the foot pumps are more efficient, but if its the same or worse than the cheap compressors, then I will buy the compressor. I am thinking of the double barrel kind of foot pump.
It will server 2 purposes - the kids bike tyres at home and for topping up the car tyres at the track. Your thoughts appreciated.
