Depends on how much 'extra' you are willing to pay. Pioneer now seems to be going more up market, so I guess that Panasonic will be rubbing their hands in glee even more, as sets like the TH42PX70 gain ground and appeal as being more affordable whilst still being a quality TV. The majority of us either won't or can't afford a high premium of around £1,500 for a Plasma TV. Yes-It's a lovely TV and I've seen it in action. Could I honestly tell the difference between it and the 4270XD ( which admittedly only has one 1.2 HDMI) ......No, and you can pick up the 4270XD for around £900 now, though the 427XD which does have two 1.2 HDMI's can be had for around £1,100.
If you want to read an indepth review which is bound to confuse the masses no end then have a look at :

I believe that if you enter 100JULAW or is 100JULYAW at checkout in the promotional code box, Dixons will give you another £100 off the TV so you can buy at £1,495, but only until 31st July 07 I believe. The 428XD has 1.3 HDMI connectivity and I guess that the DVD player to compliment it ( if you're not hagning around for Blu Ray) would be the Pioneer DV600K in Black for around £150.00.........less on some websites
