Cooking oil sprayer recommendations please

I want to buy an oil sprayer/mister to mist frying pans etc.  Not too expensive, (you know me, I don't spend lots of  money if I don't have to). The web is full of different types, mostly from China and I suspect their robustness.  I was wondering if any of you brilliant cooks out there had any favourite to recommend. At the moment I buy the preloaded unrefillable ones from the supermarket.
