I was recently looking to get one, and cheapest I could find for Europe was Korean Quoss (model 5300) brand. Don't know however if you want to go for cheap stuff for this item (there are risks, like being electrocuted). On the other hand, I think lifespan is also very limited, even for the top of the line stuff, so you would need to get one say every 5-10 years.
