I seem to get at least 2-3 big $25 surveys a year, with plenty of change thrown in along the way. I really like the program - its great, every year I can rack up enough Hilton points for a free night at a Scandic Hotel which would otherwise cost me a couple of hundred bucks.

Its a shame I dont fly AA ... because I could get more HH miles through AA conversions (or indeed free roundtrips on QF directly through AA).
