I'm new to this area so please forgive my ignorance but.. I was just about to buy a Panasonic TX32XLD500 after reading up on here and having a demo of one in a local store when I came across the new 52 version. From reading the posts on here they would appear to be identical apart from a few extra features on the 500. Can anyone please confirm to me that the picture quality of the 52 will be the same as the 500? I have seen on one site that the brightness of the 52 is much lower. I am not interested in the SD, PC input or PIP functions so feel the 52 would be a better option.
