I also prefer MTBs with long chainstays and no suspension. For the vast majority of "consumer-grade" MTBs the suspension just adds weight, and the fork dampers quit working after 5-10 years.
Some of my favorites:
Klein Rascal
(Not pictured) '85 Trek 870
'92-96 Trek 930
'83 Bianchi Grizzly. Apologies for the frame-only pic. Currently powdercoated in a slightly jazzed version of the same color, waiting patiently in the build queue.
