To me the biggest difference between the swing and the freestyle is the ability to double pump. If you don't think double pumping is your thing the swing would be cheaper. I'm a fan of double pumping as it is more time efficient. Both pumps are small enough to travel. From what I gathered from ebay prior to purchasing the freestyle, the re-sale value is reasonably high for the freestyle. I got mine from an online pharmacy through ebay for about $500 when baby buntings were selling for about $650.
