Hi, I got a 2nd hand Avent manual from my cousin, but I recently spoke with a friend who's nursing her baby and she says expressing takes about 20-30 mins each side.. so she strongly recommends dual electric pump. I'm going to keep the manual as emergency should the electric one not work. Imagine pumping manually for 40 minutes.. where's the time for rest?! Can try Evenflo, I bought mine for $179.. I think its reasonable price.
