I bought a Pioneer 42" at Costco. I don't remember the model # as I'm trying to forget the experience. 
It was like your LG. If the menu was on for 5 seconds there would be IR, and it would last for hours! It had no blacks or detail in the shadows. It was one of the worst PDP's I've ever seen. Needless to say, it went back to Costco last Saturday.
At work we have Panny 8UK's (and 4, 5, 6, & 7UY's). They very often have static images on them. The IR rate is extremely low on these... even the new ones. IR will become 'burn-in' or whatever you might want to call it, on these monitors, but it really takes some trying.
cheers and good luck huntin'
