I bought a 32" Toshiba flatscreen a couple of years ago. There definitely are geometry issues with the picture. I had a technician come over to try and get rid of them. He was able to correct some but not all. I wrote to Toshiba with my complaint. Their reply was basically that it is a general problem with the technology and you get what you pay for. They suggested I would have to move up to a much more expensive alternative. I looked at their top of the line model at that time (twice the cost) and it still had these same issues.
I like the look of the new LCD and DLP based models (size and weight is a bonus), but I feel they are too expensive still. Will wait till the price drops.
