mc13224 is the lowest cost solution that you can actually buy for real.
mc13224 is cheap because the microcontroller, flash, ram and radio are
all in the same package.

You can buy 100 for $4.45 at Mouser today. (better than the $4.74
direct from Freescale so they are discounting)
http://mouser.com/search/ProductDetail.aspx?qs=gfD5V8h1ZppSNsTByz%252bgCQ%3d%3d

Em351 is $3, but after asking that's in 10M quantity. I suspect
mc13224 would be less than $3 in 10M quantity too.

If you need USB...

TI CC2531 - $8.25 100Q at Mouser
mc13224 - $4.45 + ft232r $3.50 = $7.95

The Atmel solutions are more expensive:
at86rf230 $2.80, you aren't going to find a CPU/ram/flash for $1.65 so
mc13224 wins.

Check out the schematics at the bottom of the page...
http://mc1322x.devl.org/

External component count is basically nothing except the crystal. The
RCL circuit and 32K xtal are optional.

Mar's boards are a little expensive because he is building them one at
a time by hand.
They'd be a lot cheaper if people ordered 1000 of them.

Mar has a procedure in place for syncing to Contiki CVS. He just
resynced a couple of days ago.
I'm sure the code will make it into main Contiki CVS sooner or later.

Any thoughts on converting the Contiki repo from CVS to git at sourceforge?
