I wish i had thought of getting a second hand one when i got mine.. good ones are exxy! I would borrow both and see what suits you.. I found the electric Avent really good, but some people prefer manual as its more controllable. I just hot washed mine, and its been lent out to a few mums and come back.. they don't even recommend sterilising any more as long as it has a good hot soapy wash (though you can serialise if you want).
