Might as well go with an atmega328 20pu.  The price is very close and there is 4 times the memory and also more ram.  Otherwise the hardware is the same.  If you want a lot of power go to a atmega644 20Pu (40 pin).  It has the most power of any of the DIP chips.

The 324, the 644's little brother, has less memory but two UART instead of only one on the 644. Just a note if UARTs are important to you.

Ah, I didn't notice that. Looks like I am using the old style 644s  :-\

it's just the little brother of the 168, and 328.  The only reason to buy one instead of the 328 would be if you were manufacturing a product and did not need the extra capabilities.  That would save a bit of money in a huge manufacturing run.  You on the other hand will most likely buy a very small quantity so the price difference is fairly inconsequential.  The programing is the same for both the 88 and the 328.
