High-school electronics vocation

Looks like I have the chance to participate in a High-school
vocational electronics program.  What to teach?  The most useful seems
to be Arduino, since it's gotten quite popular.  I've never used it,
so here it goes.

I need to order an Arduino board, so want to know which one to order.
There seem to be several varieties.  Which one is best?

  - Latest: Uno[1] ATmega328[5] (main) + ATMEGA8U2[6] as USB serial

  - Previous: Duemilanove[3].  ATmega168 or ATmega328 + FTDI.

Others are here[4].  I don't see a point in getting any of the bigger
ones, so it seems Uno is best. I got 2 on eBay here[2].  Also, some
chips that are not code-compatible, but have the same header layout:

  - LeafLabs Maple r5
