I had been looking on Amazon, Sparkfun, Adafruit for cheap sensors to get started but then on a whim checked ebay. 

HC-SR501   MOTION SENSOR   $1.93
HC-SR04   ULTRASONIC    $2.03
DHT11   TEMP/HUMIDITY   $1.52

I reckon I'd save $20 to $30. 

I could save a few cents more but I specifically chose Hong Kong sources rather than mainland China.

Sure you could say "Oh you're ordering from China/HK!" But in the scheme of things, I'm reasonably sure that those parts ultimately come from China anway.

I got mine from eBay and they work fine for my purpose, which is hobby experimental stuff Not sure how they do it for the price, but the quality seems to be good enough if you don't mind the usually long wait for stuff coming through the post from China.

I'm thinking this will be a pretty good start for some hobby projects.
