Are you adjusting it for every call?

products range from several hundred to close to 2000 - I'm not adverse
to paying the higher price for the best quality - anyone have any
advice or experience

In general, the higher end units will require less tinkering and fiddling
with each call in order to get optimal separation, but from my general
experience, the cheap Heathkit phone patch is not much worse than the latest
Gentner digital box _if_ you spend five or ten minutes making sure the
levels and balancing are right on. Some of the wider band units have
several balancing controls for different frequency ranges, too.
