Workshop Update for February 12th, 2013
Finalizing chips to include in Bus Pirate education kit. Anyone know of a cheap serial ADC or DAC in through hole? We continued work on the illustrations for the above mentioned kit. 3D modeling and rendering, as well as breadboard illustrations will be available.

Microchip do cheap SPI ADCs and DACs with various degrees of accuracy and resolution.
TLC548 8 bit serial ADC, pretty oldskool, non-standard serial protocol (basically it’s a shift register)
MCP3008/3004 10 bit ADC, I2C
TDA8444 Octal 6 bit ADC
PCF8591 8 bit ADC/DAC with I2C

Maxim MAX187 (12bit serial DAC in DIP8 pkg).
Also:
Maxim MAX188 (12bit serial ADC, 8 ch, in DIP20 pkg)
MAX1243 : 10-bit SPI ADC @ 73ksps. 2.7-5.5 Volts
MAX1241 : 12-bit version of MAX1243
MAX5354 : 10-bit SPI DAC.
MAX5352 : 12-bit SPI DAC.
TLV5616 : 12-bit SPI DAC (this one is really simple: just send the data with a shift register).
Does anything speak against MCP4921/MCP4922?

THink about the cheap MCP4921 SPI DAC !
I would definitely second the vote for Microchip MCP series. Have personally used the MCP3203 before, very easy, accurate, cheap.
