Matt of SkyLabs has a nice build log about a temperature controlled reflow oven he built using an Arduino based PID controller and a standard toaster oven:

We have successfully managed to build a temperature controlled reflow oven using an Arduino based PID controller and a standard toaster oven from Robert Dyas! This is a must have accessory for any hobbyist who regularly uses surface mount components within their designs. Below we have a build log documenting the process of constructing the oven including:
Teardown of the original oven
Custom enclosure construction
Control Methods
Arduino Installation

So to start off I will outline a basic parts list of what I used:
Arduino Uno
Reflow Oven Shield
Solid State Relay
K-Type Thermocouple
230v AC to 5v DC Power Supply
Custom Laser Cut Enclosure

Temperature controlled reflow oven build - [Link]

A reflow oven is one of the most useful tools you will ever have, and if you haven’t built one yet, now is as good a time as any. [0xPIT's] Arduino based reflow oven controller with a graphic LCD is one of the nicest reflow controllers we’ve seen.

Having a reflow oven opens up a world of possibilities. All of those impossible to solder surface mount devices are now easier than ever. Built around the Arduino Pro Micro and an Adafruit TFT color LCD, this project is very straight forward. You can either make your own controller PCB, or use [0xPIT's] design. His design is built around two solid state relays, one for the heating elements and one for the convection fan. “The software uses PID control of the heater and fan output for improved temperature stability.” The project write-up is also on github, so be sure to scroll down and take a look at the README.

All you need to do is build any of the laser cutters and pick and place machines that we have featured over the years, and you too can have a complete surface mount assembly line!
