Not to intrude but I own both versions the pd170 and the gl2. the pd 170 replaced the pd150 and that was one of the things they updated was the screens internally to allow for better low-light recording. I purchased my pd170's both new one for 2600 and the other for 3200 so thats quite a bit more expensive than the gl2. you can find a gl2 for cheaper than 1400 I did. You can see the video I have shot with the sony's at rebeloutdoors.com god bless!
