Hi Sam, I have the same thoughts as you. I have not tried any as I'm also a FTM. I have plans to rent some machines to try during my 1st month after delivery before buying a permanent machine. you can Google rentals to find some options if you are interested?
My friend highly recommended spectra S1+ as its hospital grade. I bought 1 off carousell at $80 and bought my own parts.. Planning to get Eufy S1 Pro for work if i continue to BF after 3m :)
