  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

 Where are you located? That can have a large impact on the cost of
 acquiring a large 16700-series logic analyzer. For example, I have more of
 those than I need in the Seattle area. A local deal might work out well,
 but if shipping is involved that can quickly get too expensive.
 If bench space is limited, a 1670G takes up a lot less, and is completely
 self contained and easier to move around and set up. On the other hand, a
 16700-series is more flexible, and if you have space to set up an external
 monitor you can see a lot more data on the screen at the same time without
 scrolling around. 
Hi Glenn,
Thanks for chiming in.  I've seen you post often on the EEVblog about various LA.
I knew I forgot something.  I'm in the Fort Worth, Texas area. So middle of the
country length-wise but down South.  I've seen shipping on Ebay range from
"included" (which is kind of scary) to $350 and "freight".
My bench space right now is kind of limited but I'm hoping in a few years (retirement)
I'll have a bigger space to poke around in.  The 1670G is interesting in that way. 
There seems to be a pretty complete one (Options 002 and 003 - OSC and memory) on Ebay but
that's the place that's charging $350 for shipping.
