A member of another hackerspace and I have been diligently working on a resistor based thermocycler that's arduino controlled. Its in the final stages of testing now, total cost is ~$50-75 depending on the arduino and how fancy you want to get with the details. It has a wood laser cut box, and the block is milled out of a 1X3X3" block of aluminum, cooling is via a simple PC fan, heating is by resistors powered through an SSR with 120V AC so there's no bulky/expensive power supply needed. It runs 3 minutes per complete PCR cycle(you usually run 12-40 cycles in a full reaction). If there's interest I can work on getting another demo model built to show off at our hackerspace.
