Here is a 3B1 that sold for $1001 (plus $100 shipping) this month on
eBay:

So, it would seem that this system has now entered the realm of pricy
collector's systems like Altairs, IMSAIs, Lisas, etc. An interesting
development, given the fact that the consensus, quite recently even on
this group, was that this system was not particularly valuable.
I would personally like to find a 3B2/400, a system with a wonderfully
industrial and tank like aesthetic (and still quite cheap, if you can
find one: I'm in upstate NY and no individual or entity around here
could have afforded the $19,950-$34,950 a 3B2/400 cost new:

). Also intriguing is the fact that the 3B2 uses a Western Electric
processor, which is a late achievement of the same legendary WE name
which created audio equipment like the 300B triode tube and 555W
driver (among other Bell innovations). The idea of a homegrown Bell
processor is quite intriguing.
