Where to buy accelerometer

Where do you guys buy your accelerometers? I know the specs that I am looking for and I have found many accelerometers online that would fit my needs but none of them are packaged - aka they are just the chip... I am looking for something that of course has the chip but is also packaged in a case which can be mounted on something. Do yall have a suggestion on where to buy packaged accelerometers?

Adafruit, Sparkfun, Pololu, Robotshop, eBay...
