The 6811 is generally well respected, but it's more of a microprocessor
with onboard rom, eeprom, and eprom than a PIC-like microcontroller.
(the main thing being a traditional vonNeuman architecture, with 
programs
being runnable from any type of memory.)

MIT apparently designed several 68HC11 based boards for use as the core
of some robotics classes.  The "mini-board" and "handy-board" are
standardized designs that you should be able to find bare boards and
perhaps assembled versions of at assorted dealers, along with lots
of software support.   Apparently it was very handy to have the rom
full of debugger/operating system, and download small programs to
ram or eeprom to run.  There's usually some 6811 stuff on eBay...

Freescale still has (dos) assemblers and such available, although the
6811s are listed as "legacy" parts.  (are you sure you want to use a
"legacy" part?!)

I didn't check how many were dead.
