I'm considering my options on this one too - thanks for the info from all those experienced Mummies! Just thought I'd add... my friend bought an electric and was then given a manual. She said that the electric hurt like hell and she felt that it contributed to her mastitis as it drew the milk with too much force (and perhaps damaged ducts?). She swapped to the manual and said that she likes this much better as she can be as gentle as she needs to be and pause etc.

HTH
