I have the advent hand pump and love love it. I use my big double medela PISA at work and once before bed then I use my single hand pump for middle of the night and any after the shower pumping . I wear the size 27 mm flanges in the PISA but I respond really well to the advent 24 mm with cushions. I am on the smaller chest size, so if your large chested the pump might be an issues since I think you can't change the flanges
I have the double electric Avent pump. I got it on Amazon for 120 after a sale and coupon. It works fine for me. I've never used any other pumps so I can't really compare it to anything else, but it's comfortable and it gets the job done. Plus my baby really likes the Avent bottles, so aside from rotating my freezer stash I don't have to transfer milk around a lot.
