There is a fair amount of support for the AVRs on inexpensive
commercially-available programmers, and I get the impression that the
programming algorithms don't change as much from chip to chip. I don't
much about home-brew AVR programmers, though.

However, when compared to comparably-sized AVR chips, PICs are generally
more robust to less-than-ideal power rails, and in my experience, are less
prone to destructive latchup.

The choice of a microprocessor can easily start a flame-war, but you
definitely want to take a look at some of the AVR discussion sites to see
what you're getting yourself into.
