The GL2 has 3 1/4' CCDs. Panasonic's consumer models have the following CCD sizes respectively: PV-GS400 - 1/4.7' ($1500), PV-GS200 - 1/6' ($1000), PV-GS120 - 1/6' ($700). The only model Panasonic sells with a bigger CCD than the GL2 is it's professional AG-DVX100A, with 1/3' CCDs at $4,000. A few others have CCDs the same size, check their website.
Not that that's the only thing you should consider in a miniDV camcorder, but it's important to image quality.
