eBay is a good starting place. Search on finished auctions to see the 
going rate.

My first 7603 was $200, guaranteed not doa, from C&H Sales, w/o plugins. 
Since then, I have purchased the usual collection of plugins for around 
$60 each or so on eBay.  I picked up a 7633 for around $100 also.

The 7B92A and (2) 7A26 modules would probably be around $50 each 
depending on luck.

eBay has changed a lot it seems, in the last 2 or 3 years so I don't 
know current prices. 7000 mainframes are big heavy instruments but well 
worth it.

Good luck!

ps to David Minkler - got a brand new in the box 7A22. 10uVolt/cm 
differential inputs - yup, that's a real treasure!
