So after a ton of research I decided to jump in and go for the M400 over the s300i for several reasons including the longer base warranty, the third roller since I had a bit of a raised drain that seems to be an issue for the non m series. Unfortunately even though I got a decent price from Marina's which is mentioned often on these forums, it seems they sent me a used one even though I was told it was new.
It arrived with a crack in one of the wheel hubs, large scrapes in the actual sides of both wheels, and the caddy where the power supply sits has cracks. See these pictures below. Also the white Teflon rollers on the treads of the actual unit look like it has been horribly compressed/damaged. I called Marina's Pool and Spa immediately and on request sent them pictures and now when I call back it seems like they not answering my calls. When I originally spoke with the guy I asked if I should leave everything in the box at this point and wait to hear from them. His response was to wait and they will get in touch with me as its possible Maytronics sent them a used one.
I will update this thread on how this gets resolved to try to help others who may be thinking of purchasing from these guys.
