Digikey only has links to PDFs with more pages than I want to glance
over, no toolkit info.

Their home page says at the bottom "download toolkit", and it's gnu
binutils/gdb + eclipse based and multiplatform and one doesn't get the
run-around to find that info (beats Microchip). Don't expect "free" to
be open source though, they seem to have a proprietory compiler (doesn't
beat Microchip), but I'm not sure.

It's a completely different and let's say proprietory architecture. If
you have a specific purpose for it use it, but I'd expect the learning
investment to be high. Don't be too fooled by the MIPS numbers, that'll
be all 20 cores added up. Unless you write your program carefully to
make use of it you have a lot of unused silicon.

No, and I'd stick with ARM myself unless I had a very good reason not
to.

20 bucks (all American), same as the dev board, what's the problem?
(Read the tools notes, you may need 2.)
