AVR-Chat

I have an immediate need for at least four boards that support a dual-
uart AVR.  I really don't care which, as long as it's got two uarts, 
like the M128.

It is very important that the board be physically small.

I need the serial driver (max chip) and pads on the I/O pins, xtal and 
other support stuff, but nothing else.

Ideally a pre-assembled board.

Any ideas?
