There's about a billion variations of these. Re-post of the links:
http://www.dealextreme.com/p/digital-temperature-controller-66334http://www.dealextreme.com/p/digital-temperature-controller-66125The first is a REX C700, the second a REX C100, Google those and you'll be
kept out of trouble for hours. Those two are basically the same, the first
is a bigger physical size and can set to control a freezer rather than just
a heater, not sure about the second one.
Manuals here:
http://www.rkcinst.co.jp/english/product/single2-e.htm under
REX Century Series. The manuals aren't much use unless you know what you're
doing, btw, but they're not hard to figure out. The code on the side of the
unit tells you what features it has.
These are 220v, but you can get them in 12v, 24v, 48v, 120v and 100-250v.
Relay only (3A) on these, but some will control a solid state relay (SSR).
These can too if you open them up, pull out the relay and run the 12v out.
Or just replace the relay with a 10A version or whatever your laminator
needs.
The alarms are handy too, hook up a big light so you can see when it hits
temperature.
The more expensive ones simply have more options, like accept different
sensors, bigger ranges, dual control (heat & cool so you can maintain a bath
etc), network output, logging and so on.
These are fine for a laminator, and for under $20 cheaper & simpler than
anything you could build yourself. You can get timers in the same format as
well, they're handy.
