One thing you failed to include
is the programmer he will need to program the PIC. The best price for a decent PICkit2 clone like creation is about $25 shipped.
I saw you talking PICAXE in
I saw you talking PICAXE in the shoutbox and wanted to give you what I consider the bargain basement PICAXE starter package:
You would still need the necessary wire, connectors/headers/etc, battery holders, batteries, voltage regulators (if necessary), and to make some wheels as well but that would get the critical components. Use the virtual comport program from FTDI to emulate a serial connection over the USB cable (free). I’d say bare minimum you’ll need at least $60 to cover all the unforseen needs you’ll encounter.
You mentioned $30 in the shoutbox as a budget but I hate to say that will probably not get you in the door for any microcontroller as they all require some sort of programming equipment. I’d say with a cool $100 you could get a good start with any platform you want.
