I did a lot of research before I purchased this unit. I was afraid of the off brand models after reading some reviews and decided to stick with a name I recognized. The Panansonic LS50 had good reviews from experts and end users so I went with it and was not dissapointed. The picture is good, controls are fairly easy to use and with medium screen brightness you can get about 2.5 hrs of video before the battery runs down. Right now Circuit City has an $80 rebate and Panasonic has a rebate for a free airline adapter and travel case. Hurry if your in the market!
