I built one using the instructions at http://www.cedarcreeknetworks.com/heatstick.htm
. It works great, and I was about to say "sure I'll build one for ya!" Then I realized you're over there, and I'm in Tennessee :P You guys have all different outlets and voltages etc.
Don't feel nervous about attempting one yourself. It isn't hard and is very cheap. Just don't forget the GFCI and remember to let the sealant dry for a LONG time after potting the connections.
Oh and if built properly, the stick can touch the inside of a steel kettle, and you can touch the steel part (drainpipe) of the stick. Just keep it off of plastic if you're heating in a bucket.
