Hi Lee,
 
In designing my 6M amp, I also went looking for a 240 VAC meter, and came  
up empty.
My solution was to build an expanded scale meter (200-250 VAC) around a  
240>24 volt transformer, a pair of 9.1 v Zener diodes and a 0-1 mA meter. By  
using a couple of pots in the circuit, I can adjust everything so that it's 
very  accurate, and a whole lot easier to read than a 0-240V scale.
I used Jim Tonne's quite wonderful program Meter to get the meter scale  
right.
If you'd like, I can shoot you a copy of the schematic for my expanded  
meter.
