Well, I don't know if you itemize when you do your taxes but breast pumps and pumping supplies (parts for the pump and breast pads, etc) are all tax-deductible as well. No need to wait until January 1st or to deal with an insurance company dictating which pump you can get.
I loved my Madela Pump in Style and used it for two babies - my first I exclusively pumped for a year, while working! I would tend to buy a Madela as well. If that is not feasible and you must chose one of these then contact a local lactation consultant or your local LLL chapter and see if they have any advice for you.
Cheers! C.
