This caught my eye in Focus DIY the other day, any one tried one?

http://www.thinkgeek.com/gadgets/tools/69d3/

That is a US site, available in UK from JML Direct (just change the $
to =A3, I think the Focus price was even more...). JML's site uses
forwarding so you can't post a direct link to a product.

I thought it might have been some cleaver ceramic heat element but
looking at the Think Geek images and description it looks like it
works by shorting the cells through the work piece.
