It is too bad there is no modern equivalent of a parallel port for
exactly this sort of project. But that's the only thing I miss about
it!
A PICkit 2 programmer costs under $50 and integrating the needed six
(really five) pin connector into your project is dead easy. To me,
that seems to meet any reasonable definition of "low cost, low
hassle".
