GH2 Which lillput for Gh2 668gl or 667

[kopan]

Hi everyone. I am thinking about external monitor for my GH2 and my choice is Lilliput 668gl. I know it has built in battery (which is good and bad, couse replacing battery is a little complicated during the shooting, because of the screw) another one in 667 which has external battery and i can use exactly the same which i use with my 160 led light. So both of them has good and bad sides.
My question is:
1.Are there any other differences between them?
2. Does gh2 has any problems with those monitors? I mean according to my knowledge GH2 has full hd signal during recording so I will see on the monitor exactly what i am recording. Will I see also parameters of exposure?

Where did you buy your lilliputs guys? Amazon, cooled.com or any other?

Thanks

I got the 668 one (the one with the removable battery) off amazon and I haven't used it too much yet but just don't expect to be good for anything other than framing your shots and focusing. Trying to get a good read on what's actually being recorded (colour-wise) is a no go.
