Hi Chris,
i would say if the choice is between beovision and BC1.
Go for a Beocenter 1 its handy for small spaces due to the turning feature. And very handy because it has ( TV/Radio/cd/dvd/speakers) all in one !
One control and all in one place.
As mentioned if you can get one which has been already refitted with an up to date dvd player you can have a good deal.
Also take in account that certain models can not be upgraded with sw. that for instance can upscale streaming movies from dvd. Otherwise your mother will have a very small window to look movies in.
The latest BC 1 version can also play burned dvd and cd`s so its important to ask if it can do all these features.
Also the fact that you can plug in real easy comps and camera`s from front makes it a great monitor in the good sense of the word. It`s real easy if you want to show your mom pic`s video etc you just made and show them large on her tv set.
Its an unique system ,.....they missed out on its upgrade I believe.
