Pioneer Elite vs. Pioneer "Standard" Kuro Plasmas

My primary question is weather or not the "Elite" models are worth the extra dough ? Does anyone know if they can both be ISF calibrated ?

Thank you
As a Californian I saved almost 2K on a 151FD, great pricing, no tax, and free shipping from here.

No buyers remorse here.

there are certain things in life....that are truly love at first site! this is one of them. I've had my Elite [50"] going on three years now. It's A daily performer that has had zero operating issues to date & IMO I've still not seen anything that can touch it in the way of performance, and value (within it's price range) Additionally should you match this up with a serious Blu-Ray like Elite's BDP 09FD, it's game over! 1080P. So If you can step up to the Elite it's a no brainer. Go for it, and Yes ISF on the Elite
I have the Elite 60" Kuros 150FD and it blows away everything I have seen.

Ad a major step up over Pioneer.
I have a 5080 Kuro (non elite) and just ordered a 151FD last week. My ISF guy told me that if I could swing for the elite to get it over the non-elite. This was not as much the case when I bought the 5080
