Just spoke with my insurance and the medical equipment supplier and I'm coming to you all for advice.

My sister gave me her Medela Pump In Style Advanced. She used it for 1 year with my nephew as a WOHM. She did say they wear out, so if I can get one free from my insurance, I may as well.

My insurance will provide a double electric for free. The company I called (good reputation so I'm just going with what they said) told me my options are:
1) Medela Advanced Personal Double Basic-- no battery pack included, electric only, completely covered by insurance.
2) Upgrade to Pump In Style Advanced for $50. Included nicer case and battery pack.
3) Upgrade to Freestyle for $100, with all the bells and whistles a Freestyle comes with.

Considering that I plan to be a SAHM, and I already have the used PISA, what would you recommend? I'm thinking just go with the free one, for use at home, and I can use the old PISA when I travel and may need the battery? The freestyle sounds awesome, but since I won't be working outside the home, it doesn't seem like I'd need it, right? Moms who only pump occasionally, what say you?

The options are listed out on this site if you want to look:
