Boards (which one?), or chips?
Propellers are interesting chips, but pretty weird. Probably not for beginners, given the general difficulty of multi-core processing.
(I may have to visit my radioshack...)
The P8X32A QuickStart board... Their weirdness is what drew me to them(the low price did help though!) I like the idea of multiple simultaneous threads but there doesn't appear to be anywhere as much sample code by comparison...
