Compability with Parallax

Hello,

I would like to know whether Parallax sensors are compatible with the Arduino Mega. Some of the Parallax sensors I am wondering, whether are compatible is the ones in the Parallax Sensor Sampler Kit. The Sensor Sampler Kit can be found at http://www.parallax.com/Store/Sensors/AccelerationTilt/tabid/172/CategoryID/47/List/0/Level/a/ProductID/468/Default.aspx?SortField=ProductName%2CProductName.

From just a cursory look all those devices appear to be electrically compatible with an Arduino.
