Good morning
I am sure a multistandard modulator will be a compromise solution
.
Look at 625.
The DF modulators used today make trouble in the
sound if you use a parallel sound set and vise versa
.
If you want a perfect picture and sound you need
a special modulator for every standard
.
So I think for those who only use 405 and want to
buy something compleatly finished,
Malcolm's " plug and play " is still the right choise
.
For the others there are kit's avalible or they
can build there own modulator like me
.
I can build a finished modulator for every standard
but it will be very expensive and good, of course.
Kind regards
Darius
