Regarding the threads on carrying a kettle. A while back I had an immersion heater. I think it was bought from the RAC in Aust. I'd just stick the thing into a cup of water and boil it. Thing was ideal for travel as it was small & light. Don't know what happened to it, probably some Thai shelia took a liking to it. Anyway, worth picking one up if you come across them.
You can buy them in most of the hardwear shops in BKK and Pataya for a few Bht but are a pain to put anywhere after the water has boiled in the cup as the stay hot for a while.
I think we brought a kettle at a 7/11 for abour 300bt. Well worth it. If you intend returing to Thailand , bring it home as it does not take much room. I already have mine packed!!!
