Breast Pumps (Spectra)

Anyone have experience with the Spectra breast pump. I see some positives are that its medical grade, tender on the breasts, easy to use and hygienic. The downsides with this one are that it is not really popular and all parts have to be purchased online. Also, does anyone have any recommendations on breast pumps? Specifically ones that I may be able I use with other brands bottles in case I receive different brands of bottles?
