I got a thermostat on eBay and wired it inline on an extension cord I had kicking around. Plugged the freezer into it an dropped the thermostats wire/gauge into the chest.
To be more accurate: It was 13.69 with 50 cent shipping. Here is a pic of it.
The wiring was as easy a could be and the thing arrived about 6days after purchase. Never having done anything like it, I am very excited to have saved so much money.
