I have a 42PW23P. It's well worth the money... what other 42" display can you buy for £1K? (maybe a refurb LCD PJ, but IMO bit of a lemon if you ask me)
I've had this set for about 6 months now. Overall I would say it's worth it., with great picture quality. it has a couple of small quibbles, but everything has something. At least with a CRT RP I can sort out any geometry faults (ie bendy lines) with a 36" it's not always possible- theres only so much you can do.
I would not recommend going into the service level unless he's technical-minded. You can screw the set up.
However the picture does improve performing the full service level convergence - for PAL & NTSC modes; and all aspect ratios. Disabling SVM also helps.
Here's a snap shot from my RP (looks ALOT better in the flesh, lots more detail, and more in focus, with even brightness in the corners)

I have a pure Region 1 DVD player into AV4 (Component) a Region 2 into AV1 (RGB) VCR into AV2, and MC-1 OSD/switching on the AV3 (front S-Video)
Sound is quite good for a TV.. loud and clear.
RP's have come along way since the naff Philips RP's that are in Game (bright in middle, dark on the outside).. my set has even brightness all over.
Oh if you're gonna use Region 2 PAL DVD's I would be careful, as three people can see the 50hz flicker from PAL DVD's (with Region 1's they're fine, as NTSC refreshes at 60hz) Since 100% of my collecition is R1 NTSC, I'm not bothered. For broadcast TV we see no flicker.
If you notice the flicker, best to go for the WT version - DD, Freeview & 100hz.
One important tip- make sure you decrease contrast from 100% to about 40-50% - doing so will lengthen the tubes life, decrease the possibilty of screenburn, and it make look much better. Also reduce colour to ~35.
The TV has it's own User Level convergence, that option is fool-proof (however it's not as good as the service level convergence)
I have also done other tweaks- adjusted each CRT electron focus (screen) and each CRT lens focus.. these are quite advanced tweaks so only for the experienced user.
I would recommend getting a copy of Avia DVD - NTSC only though (checkout the powerbuy section) as this can be used to set the TV's brightnes/contrast/colour/tint/sharpness settings, plus check geometry & convergence alignment.
