I have a different Brother embroidery (only) machine that was my first intro to machine embroidery, and I have upgraded to a larger Baby Lock, but keep the Brother around as a backup and for smaller projects. I've been happy with it, but haven't used it much. On this Innov-is model unless I really wanted those Disney designs, I'd want to know if they're costing me more than I'd pay for a similar machine that doesn't have them. Whether it actually does, I don't know. If the websites that sell this model have customer feedback that would be something you could read through, but take with a grain of salt because most people review things too soon after they get them. About all I can really contribute is that I have a favorable impression of Brother machines in general.
I did a quick search for a mag hoop for the Innov-ís NS2750D and did not find one. I don't know if they make magnetic hoops for this machine, but definitely find out before you buy. Not all Brothers have the same design where hoops attach.
