Sigster: It depends on your learning style & experience of course, but I STRONGLY recommend you start really simply with PICAXEs. I've had countless emails since 2002 (!) from frustrated users immersed in 28/40 "rocket science" stuff, & in many cases they'd answer their own queries by FIRST getting a feel for things with a breadboarded 08(M) flashing a few LEDs etc. Stan
