Thanks for all the replies. I would like to have about 10 samples. I have MKII programmer which allows me to program firmware through the SPI interface. The firmware only needs a timer to write to PIOs at certain timing.

As others have mentioned, ATTiny85.
Internal 8Hz Oscillator makes this super easy to use.

You can have 25 for $20.25 USD, which puts it at $0.81 USD per unit.

Easily programmable and easy to use.

Here's a recent project I used it for to give you an idea how simple a circuit with it can look:

The ATmega8 is hard to beat at eBay prices, if you're willing to risk eBay suppliers.  (I bought some a long time ago, and they seem to work fine...)  Note that the mega8 is more "directly compatible" with Arduino than the "tiny" cpus; no special installs needed or anything...
