A full BF mom's recommendations:
Electric Pump: Medela
Manual Pump: Avent
If you're going to stock up milk in Freezer, better use milk storage bag, otherwise, you have to buy a lot of bottles. If you just pump out for immediate consumption, no need to buy storage bag then.
For milk storage bag, recommend you to use LANSINOH ($54/25 bags/box); ie pump into the bottle and pour into the bag for storage.
I've saw someone selling BOOTS milk storage bags in 2nd hand market ($60/40 bags/box), you may consider (I haven't use BOOTS before).
