The pump in style (regular/not advanced) worked for me. I bought it for baby #1 in April of 2003. I used it heavily for 12 months and I am on month 6 of my second baby. I work 60 hour weeks and both were exclusively mommy's milk fed. So I strongly recommend this pump and can vouch for it's durability. The only reason I don't have the advanced is becuase it wasn't available when I was buying mine.
