There are many newer versions of the PV-500. A new one comes out about once a year, so you need to do more homework. The best way to find out what video MSCs demand and which PV-500 models will deliver ir, reliably, is to ask those MSCs what their owners/staff would buy if replacing their current equipment.
The odd thing is, my pre-2010 models are actually worth more used than most of the newer ones are new. Reason: extraordinary reliability with high quality picture and sound.
