I found one on Amazon for $10.

It's basically the same thing, right? I think they have a double one for around $30 too. I imagine it would work just as well as the expensive models as long as the suction is there.
Edit: Here's the double one on ebay for $21: http://www.ebay.com/itm/SMP-Size-Matters-Pink-Breast-Pump-Enlargement-Enhancement-Kit-Suction-Cups-Bulb-/350507841958?_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D4%26po%3DLVI%26ps%3D63%26clkid%3D5840880998689846921
