Looking for the Tek 465 of Logic Analysers

Hi Tony,

I don't mean to throw shade on your HP 1630 or your K100 ... just in my own
personal opinion, when I see a HP 1630 on eBay for $100 or a HP 1660 on
eBay for $100 ... and you see this all the time ... I think going with the
1660 is the better deal ... you do make a good point about schematics and
repairability ... and hack-ability ... there are plenty of very exotic
looking components ... especially on the acquisition cards ... on the newer
machines that I'm sure are basically impossible to repair.

I just try to manage that risk by keeping as many spare cards on hand as I
can get for the 16500 series, and I've always got the 1662 standing by in
case something happened to it ... honestly, when you can get a HP 166x for
$100, unless you enjoy the sport of troubleshooting and repair in and of
itself (and I do so sometimes myself) is it really worth sinking much time
and effort into repairing a 1630 series, or a K100?

I just want folks to be aware ... people might not necessarily realize,
what their money will get them; I'd hate for someone to shell out for a
1630 when they could have gotten a 166x or 167x for the same price... That
almost happened to me when I was shopping around and I would have regretted
it. I'm glad I did the a little bit more background research beforehand...
No intrinsic dislike for the classic instruments; if you got em, use em! :O
