I think some people have a susceptibility to seeing the 50hz problems. Canvassing opinion from VT20 owners may not be helpful to you, some owners just see the issue less. All you can do is visit another dealer and see if their stock presents the problem to you.
In my particular case after 2 bad V20s, enough was enough. In no way was it subtle the way motion was cocking up.
I had a polish guy ask my opinion on what he could get instead of the VT20. He had seen the 50hz problems first hand and was not amused. He is more than happy with his 54" Z1 he bought instead. I have the 46" Z1 myself, there is some remaining stock of both if you search hard enough, A 54" can be had for £2099.
Other than that I would wait until new models surface in Spring, but they usually release the low end models, first, Can you really wait til June? hmmmm
54 Z1 beyond my budget and 46 too small. I think, 50hz problems aside, the Z1 would be a backward step.
Can't really wait till mid 2011.
