I have had Samsung mx20 and Panasonic s26 and JVC 330 sd camcorders , and the picture quality was very dark on the Samsung with poor detail , Poor detail on the Panasonic S26 and the JVC 330 was not much better.
But i bought an JVC GZ-MG430 and the picture quality wipes the floor with the rest of the sd camcorders i have used, I cannot find any info on the JVC website on this camcorder , but the manual is available.
