[cctalk] Logic Analyzers - HP/Agilent 16700B or 1670G?

Hello all.  I looking around for a Logic Analyzer for doing (mostly) DEC QBus/UniBus stuff.  Being the way I am I want something with enough lines to handle the most of the signals so I'm guessing something with roughly 80-ish channels.  I think that lets out all/most of the USB based LA.  I've looked around and it seems the the HP/Agilent 16700 series (16700B/16702B) are probably what I want.  I've also seen the 1670G which also seems quite doable.  I've seen a lot of posts at the EEVblog and it seems I missed possibly the golden age of 16700 LA by a few years price-wise. What I'm wondering is if there is something specific I should be looking for, or opinions on which LA is more suitable.  Or even if there is a different make of LA to look for. Thanks in advance for your help John H. Reinhardt
