pricerunner.com shows DVD players from £17.89 to £2495 (I'm not counting
the three outliers at £10,001 and £20,001 and £35,001 because I assume
someone's mucking about with the database :-)).

Interestingly VCRs are still available and they run from £31.89 to
£599.99. Obviously there are far fewer VCRs than DVD players (or
even DVD recorders I guess) and only two (both from JVC) live in
the >£150 bracket.

I make no claim that even the expensive ones will be well made, but
expensive ones do exist and, for DVD players at least, they are
not thin on the ground.

I know that service manuals are available for Sony and Philips stuff
and I see the odd JVC manual floating around on the net. I don't
know how much they are to buy (as I've never needed to ask) but
they do exist. Obviously anything modernmay well have custom Ics
but then again a few of the manuals I've seen suggest that at least
some of the ICs are common to multiple manufacturers units (i.e.
they are made by someone other than the manufacturer and sold to
anyone who wants to use them). They are not general purpose Ics
and are unlikely to be used as anything other than their narrow
intended purpose (e.g. random DVD processor or whatever) and
they may not be readily available ten years (or five years) from
now. But they might be (after all, valves still turn up as NOS).

The thing had better last a good deal longer than the warranty as
otherwise
I won't be buying from that manufacturer (or even quite possibly the
online store that sold me the goods) and I'm not alone in that. Perhaps
I take it a little further than many others, but I know plenty of
"run-of-the-mill" consumers who get cheesed off if their music centre
packs in after a few years. I'll admit that they may well go out and
buy a new one two-four years down the road, but if they keep it, it
has to keep on working. (I'll admit that this generally does not seem
to apply to mobile phones - no idea why not).

Well for a start it is available now :-) If you don't want it, then 
that's fine. My Philips TV is about six years old now and gives a
better picture than the DECCA Series 80 chassis that it replaced
(although I'd still be watching the DECCA if the tube had not
decided that enough was enough). If it breaks I might fix it
(assuming its feasible) or I might replace it with a new flat screen.
My £30 DVD player gives perfectly satisfactory results (maybe if I
had a 37" TV I'd think differently, but I don't ...) and my
cheap (£40) VCR just keeps going (despite kids deciding to shove
all sorts of garbage inside it, seemingly for fun). I'm not claiming
they'll last 20 years but the VCR has made it to five or six so far,
so I'm happy.
