I have an Ameda Purely yours that I like. Its a double electric. I also have a Medela hand pump that was good for occasional pumping too.
As far as the $$$ goes...talk to your insurance. Some of them will pay for all or part of a breastpump. Or you can look into renting one from the hospital - sometimes that actually works out cheaper. But whatever you do resist the temptation to buy a used pump. Its really not safe.
