super bargain basement one from Argos
i use same and find they work a treat. they do get hot but don't affect performance
I think this is probably the same (very sound) theory that a carpenter friend explained to me many years ago : when I asked him why he used a domestic Black-and-Decker drill rather than a Bosch Professional, he said they both did exactly the same job but when the Black-and-Decker died, all he had to do was throw it away and buy another one. With the Bosch Professional costing an arm and a leg, he would have felt obliged to have it repaired, and that would have cost more than just buying a new domestic Black-and-Decker. I think the same is probably true for stick blenders : if you can buy them for GBP 3-99, you don't have to worry if/when they die from overheating; with a Bosch at around GBP 49-99, you couldn't afford to burn one out, you would therefore have to use it rather more cautiously, and it might take even longer to achieve the right consistency than using a cheapo without a care in the world !
