Thanks for all the responses and suggestions! I ended up getting a Swing single electric pump. I'm so happy I did because that pump is better than my PISA (well except that it's a single of course!) I like the new Medela technology seems to be even more effecient.
Re: f/u to single / manual breast pump ?
Don't get one, they suck.
You might have better luck with them, I don't respond well to any pump.
