hi, i have the avent isis electric pump..... my mil bought it for me when i had huge cracks and wasnt sure if i was going to continue b/feeding. i couldnt get it to work in the early weeks as i was so stressed about etting it to work, but i have expessed after isabels morning feed for the last 3 days and have found it absolutely wonderful. isabel now sleeps through the night so i wake up a bit engorged and isabel isnt hungry enough to empty both boobs....

i agree with the others though, perhaps just continue with the research and make the big purchase later if you decide to go down that path. you will be more concerned with establishing bf at first and that can take a while......
