Canon put the same lens that is in the GL2 HD camcorder into the Vixia HFS100.  That alone should make you pause.  Another great thing about this camera is that it stores on SDHC flash memory cards.  So, unlike hard drive hd camcorders, flash memory is not so prone to failure.  And that is a big deal when you are moving the unit around so much.  Also, the camera delivers unbelievable still photos (8 MP!).  You get a 1/2.6-inch, 8.59-Megapixel Full HD CMOS Image Sensor that is capable of 1920×1080 Full HD rendering, compliments of the DIGIC DV III processor.  Also comes with 10x optical zoom and a 2.7 inch lcd screen.  And, of course, the Vixia HFS100 Canon HD Camcorder is very highly rated by consumers.  You can fetch for around $1000.
