Hey man, vangelis brought me to the work of PKD as well. Personally I find Electric sheep to be his most accessible work but certainly not his best. Probably the #1 choice for adaption to film, with man in the high castle taking a close second.
I would really love to get a heady TV show of VALIS, sort of like how they do the monologues in House of cards, but with a driveling Horselover Fat in front of the camera breaking the fourth wall.
Sorry for the rambles, I don't meet a lot of PKD fans outside of my close friends group.
