I've got a rebadged Sony GDM-20E20 and GDM-20D11
that have some issues and
Just FYI I have yet to get a repair estimate on any of the problem
Sun monitors I run across of that model type that don't more than
double the replacement cost of a working used unit. People I know
that deal in a lot of this model used don't seem to bother to repair
them either, and they are pretty darn cheap, and not without
resources.
OTOH I sure do like my 20E20, and haven't had a bit of trouble with it.
