Thanks to everyone. All of this has been very helpful information.

I'll go with the ATmega16 and upgrade my thinking from avra to the gnu toolset. I expect I'll be ordering some STK500 JTAG adapters from Ecros Tech too. :)

I agree completely with this. I also think that the selection of JTAG is correct because you can do everything (set fuses, program and debug) in a "seamless" fashion (at least in AVR Studio, probably also with the right Linux tool set). Plus, you can't brick the device by setting the clock fuses incorrectly. The ATmega16 also has a good set of peripheral functions, but the data sheet isn't overwhelming, as data sheets of the richer devices could appear to students. Finally, if you need more RAM or Flash, it has a big brother in the ATmega32.

Graham.
