I had the Monster 1000 for 6 years but not enough input after I upgraded my system recently from 8 units to 14 units. The lowest quote I got for the Monster is $1,300 now. But I happen to find a similar version of 1000 by Belkin , name 'Pure AV isolator', which also had 8 designated input, but only cost $800.
The quality is as good as Monster n the build is even better.
