I had a 1084, right now using a 20" sony PVM with the Amiga kit db23 to 15 pin VGA connected to db15 to RGB RCA cable. Composite out from the A600 prvoides composite sync to the PVM
It's a nice 20". The only caveat is it's NTSC it will display pal but you lose some of the display at the bottom.
got mine for $50 on ebay.
