I've had 2 Panny's and 1 JVC over the years and my favourite by far is the JVC--but that did take me 3 years to save up for. Of the 3 that you mentioned, I'd go for the AE7000. Panasonics have always had great placement flexibility and lots of features, but like all LCD projectors the light paths are not sealed. I'm a clean-freak and I was getting dust blobs in my projectors every few months. I got tired if cleaning them out and decided the inky blacks, superb colour and sealed light path was worth the extra cost of the JVC. I care not for 3D, BTW, so my opinion is based purely on the 2D capability.
