I would say the ST50 is practically at par with the VT30 in terms of image quality (the difference in built-in sound system can be regarded as trivial perhaps)
Pero kung di ka masaya sa ST50, there is always the GT50 and the VT50
Panasonic skipped "4X" dahil sa pamahiin.
Since the VT30 is selling for less than 40K, hopefully ganoon din maging street price ng ST50 when it's finally released. Kaso, I think they are essentially dumping the 2011 models at the moment. Thats not bad if you are talking of the VT30 though.
ST30 owners who bought from SnS, isip-isip ng upgrade via Vic if possible. Good chance!
What is the 2012 counterpart?
