Spectra Breast pump

Has anyone tried the Spectra Breadt pump?? I'm a FTM and hoping to breast feed. Looking at going with the spectra s1 pump... It is a closed system to help prevent bacteria issues, and also is a hospital grade system, looks to be cheaper than the medala system anyhow even though I plan to get through my insurance. Just wondered if anyone had any experience or comparison between spectra and medala?
