if you want something that will be in the same ballpark for overall picture quality
vt60(hasn't been made in over a year, little to no chance of finding one new)
zt60(same as above)
f8500(at the end of it's life cycle, could be difficult to find)
*f5300/h5000 may be 'close enough' to the vt50. and they should give you better motion than the lcd's on the market.
oled, whatever their current model line is, but motion is not one of it's strong points from the reports i've read.
unfortunately, that's basically it.
