I understand the that the th42pa20 has a tuner, the th42pa20 picture has looked the best I've seen in most stores, but I haven't as yet seen a PW6. I am looking for the funtionality that the th42pa20 has in terms of picture in picture. caching of teletext pages etc and in the stores Ihave been to nobody can answer whether this a a product of the tuner or the screen. With the PW6 coming in at £2550 and the th42pa20 at £3200, is the difference worth it with the add ons required for the PW6? Any help appreciated.
