When I was researching which pump to buy for when I had DD, I searched this forum and stumbled upon a thread that had a link to another thread/blog/website that listed all the types of pumps and brands available and discussed identifying your pumping needs before buying one. It was really useful post. The only thing I can remember reading was that I should buy the pump on ebay.
Does anyone know what I am talking about?! Would love to find that post/blog/website again...
I'm not sure I'd buy a pump from eBay unless it was designated as unused (many are listed as that, but when you read the description the seller will say used once or twice) or if the unit was a closed system (like a Hygeia pump.)
