Panasonic's trio of prosumer camcorders, the hard-disk-based HDC-HS900 and flash-based TM900 and SD800, deliver generally excellent video quality and provide the full set of manual controls and features advanced users want. But you have to be willing to baby the white balance a bit. The TM900 is my top pick of the three for its EVF, but if you're on a tight budget the SD800 should suit just fine.
A functional trio of camcorders, the Panasonic HDC-SD80, TM80, and HS80 are notable for their manual exposure controls (unusual for their price class) and well-designed touch-screen interface, but otherwise you can find better options. Of the three, the SD80 is the best choice simply on price.
Panasonic's quartet of entry-level HD camcorders--the HDC-HS60, TM60, TM55, and SD60--delivers a nice manual feature set and good performance, as well as solid video quality for their class. As long as you don't pay list price, the SD60 is a great value, and if possible, avoid paying the unnecessary price premium for the hard drive in the HS60.
A very good prosumer HD camcorder, the Panasonic HDC-HS300 still isn't as good a deal as the similarly featured but flash-based TM300 and has the same annoying touch-screen interface.
A very good prosumer HD camcorder, the Panasonic HDC-HS250 is the best deal of its product line, but has the same annoying touch-screen interface.
