Anyone with twin products advice please??

I have tried not to think too much about accessories & needs etc for the care of twins, but now I am realizing that it isn't helping & that I need to settle my O.C.D. mind & move on. :) I am 26 weeks along & 12 weeks at most left. I feel as though I have no control (and for those that don't know me that well, I am a bit of a control freak) over the future, but having some preparedness might help me relax.. a little :)

I am having an internal debate on car seats, strollers, nursing, bottles etc. 1st on my list is strollers. I need something in the beginning to hold 2 infant seats. Originally I was going to go with the Graco Quattro Tour Duo glider ($240) & matching car seats (each $130) approx. $500 total.

BUT then my friend offered me her Snap N' Go which would leave me to only buy the 2 car seats for now. Eventually I would still need to get another stroller. I can't remember, is it 6-9 mo's or so when you get tired of carrying car seats in and out? At least by about 20 lbs I guess

So do moms of twins prefer a side-by-side stroller (hard to get through doors & through isles) OR a front and back stroller (long and awkward when trying to open doors)?

Bottle preferences? I used Avent & grew to detest them because of the 90% leak factor. It drove me crazy!! Any word on Dr. Browns or Playtex or Born Free??

THX for any advice!
