It seems that the new Panys are getting good reviews - the PX70 and 700's
They are being priced quite competitively too, at under £1000 for a 42" PX70 - have seen prices of sub £900. The 700 isn't available yet, but will probably be 250 - 300 more (same screen technology, but with more connections, and a better sound system).
They are replacing the PX60 and PX 600 - which were widely considered as the best plasmas pound for pound.
As said earlier in this thread avforums is a great resource, for the plasma board see

If you are planning on over 32" go for plasma, if you are going for 32" or less then go for LCD. For HDTV you really want to be over 32"

Oh and another thing worth knowing -
John Lewis will price match other stores (has to have a bricks and mortar store - but some online ones do - e.g. empire direct).
Then you get the tv at the best price, but you also get JLs 5 year warranty.
My mate saved over £300 using this price match facility.
