Electric Coolers for Mash Tun?

[craigevo]

Just wondered if anyone ever tried using these electric cool boxes as a mash tun ?

If it heats then surely that would be great for a mash tun, I presume they wouldn't have any thermostat, but you could probably put the power plug in a timer and get it heating for, say one minute in 10 ? May even be able to do a step mash.

I've been thinking about these too; I've seen others that wil supposedly go up to 70'C; I reacon a bit of adjustment and they'd perhaps go to 75'C
