I found those at $28 each (qty 1), but that seems pretty high for a
microcontroller. That's at least half the parts budget, for most of the
projects I am thinking of. So I still have the "where" question :-).

TQFP-144...I guess I could figure out how to attach that to my homemade
PCB...something tells me you have way nicer tools than I do.
