I still believe the Victors were the best chargers ever made, in terms of features and capabilities, but they were somewhat known for unreliability, so you might not want to spend too much for one if you're going to get one. I wouldn't trade mine for anything.
If you're shopping for one, you want to get the Super2IQ or later (IQ3 or IQ3000)
The earler models were great, but didn't offer all the features of the later revisions. I don't know which model first allowed you to set the peak threshold, but I know for sure the Super2 and later did.
There's not much info on the web about the Victors anymore, but there's a site run by Sam Capri up in Canada which has some info:
Sam used to do Victor repairs, but I'm not sure if he's currently doing them anymore or not. You'd have to email him to find out. He's probably also better able to answer any specific questions about the various revisions.
