Ron, what timing!
This last week I was looking to replace
my car cassette player with another one but cheaper
(another Prius may be joining the household this autumn).
The prob that I was running into was that they are SO cheap,
that if you decide to have someone else install it (Best Buy, Fry's...heck,
just about ANY stereo store), you'd end up paying, for example $40 install on a
$50 - $75 deck(!) Also, try to find someone with more than 1 or 2 in stock.
My regular place up near Sngry's house sold their last one 3 weeks ago
and said that they could special order.
Anyway, for the old car, I'm going real basic CD/mp3
with a direct out for a future iPod if I decide to get one.
Appointment in Plano, TX on Monday @ 1PM.
Maybe if you self-install, then a cheapy could be the way to go,
but you can get a basic CD unit at about $150.
