Ammeters and Voltmeters

Hi,

I'm wondering what is the best source for voltmeters and ammeters 
(such as for a control panel)? They probably come up on e-bay on 
occasion, but is there any sure source that coilers like to use or 
find work well?

I have a DC ammeter as well as a DC voltmeter from an old piece of 
equipment, but I suspect that it's probably not possible to convert 
them to AC...is it?

Thanks,
Greg
