The average display diagonal of medium total megapixels camcorders that were released around the same time as this video camera is 2.8", and the display diagonals range from 1.5" to 4". At 3 inches, the GZ-GX1BEU has a quite large display diagonal compared to most of the other medium total megapixels camcorders that were released more than two years ago.
Alternative 3" screen size video cameras currently available that you might want to consider include because of it's better review score, the Sony HDR-PJ260E.
If you want a camcorder with a larger display diagonal then you might want to look at the Panasonic AG-AC90 (£1,701.19) (3.5"), or the JVC GY-HMQ10 (£2,394) (3.5").
