Here's my two cents. I honestly feel that the rate at which TVs are evolving is like how PCs and laptops were evolving 10 years ago. Your unit will basically become out of date in 5 years time, so no point buying a TV that you hope will last 15 years. For example, there's a strong chance that in 4-5 years, OLED TVs will give you a level of picture quality that even current top end models will not give you at twice the price.
So, I would say that if you are not satisfied with the picture quality of the high end LED models at the top of your budget, you might be better off paying less money and going for a more standard 42" model that has say, a higher refresh rate.
For what it is worth, I have an 42" LG that I bought for a fairly good price. While it doesn't have the greatest picture quality in terms of deep blacks and what not, it actually has the best sound I have heard (which means I don't have to buy a separate pair of speakers) in any TV. I'm not asking you to buy because I made a similar choice, but I'm just saying that in the long run, I've found that picture quality is not the be all and end all as long as it is "good enough". Ultimately, it is about finding the model with the right balance of features and strengths that works for you.
Note: I've also found that while deep blacks are not great on my TV, I find it annoying ver rarely say, once in a month, and only when I am watching a movie that is exceptionally dark.
I've also found that picture quality actually depends more on the quality of broadcast than the TV itself. I actually moved my TV from India to US, and I have full HD broadcast for all channels here. The picture quality difference is night and day between full HD in Comcast and SD in Tata Sky.
