I have visited few places and was not able to see display model for 42XT50 however can see 42X50. Seems it will take time to get XT50 or UT50 on display. However I could get following rate (not negotiated):
42X50: 44900
42XT50: 50500
42UT30: 54000 (yet to get more details. But its fresh piece and not display one)
In one of showroom I could even see 42v20 (which was rare to see). It was not even in same shop sometime back. Sales person said its been placed on display just 2-3 weeks back and rate offered was 65000
Sales person also informed about display piece for 42st30 in some other shop and rate was quoted of 57000
However told that I will get warranty from date of purchase.
One of my friend informed that if you are not going to select panny ST series onward then you can even think about sammy in entry level plasmas (42E490.)
I am bit confused now...
V20 : 2010 model.........a top of the class Panasonic's hi end award winning tv
ST30 : 2011 model..........excellent performer, one of the best tv available
UT30 : 2011 model.........entry level 3D tv full HD
UT50 : 2012 model.........entry level 3D tv full HD with upgraded brighter panel
X50 : 2012 model...........entry level 2D HD ready plasma with upgraded panel
XT50 : 2012 model.........entry level 3D HD ready plasma with upgraded panel
I would steer away from UT30 and look at any of the 2012 models. Best would be to go and demo the tv's and then finally decide. Just for info the series go like this from top to bottom : VT, V, GT, G, ST, S, UT, u, XT, X..........so X is the basic entry level while V sits right on top being the most expensive series.
Earlier with the X30 Panasonic did not have any good entry level plasma's compared to samsung but with the launch of the 2012 line up things have changed and both X50 and XT50 are excellent tv's perhaps even better than the entry level tv's from Samsing.
