I have one! Mine is bigger than a sewing machine. It is a Brother Innovis NV800E so maybe more than you are looking for but youtube has a million video demos of the machines and also people using them showing you different designs and how to embroider towels or float the design rather than hooping it.
If you can there are places that sell sewing machines and embroidery machine and they let you have a play on them. See if you have one local to you.
How mine works using different colours, you load the first thread colour, it does all of the design in that colour and you move onto the next one. As for how easy it is to change the colour you literally leave the machine going until it beeps at you to change the colour. Mine has low bobbin alert etc so you can pause the design to change it and it finds exactly where it was. You can also rewind by single stitches if the thread snaps (stops automatically) or if you want tog over an area.
Threading it up is as simple as a sewing machine, the needle threads itself too automatically on mine.
The restriction is the hoop size which sets a limit on the design size. My friend has the larger version of mine. She has two DDs and constantly embroiders designs onto their clothing which gives it a unique element including Disney characters or font. There are plenty of free designs, sometimes you can buy packages.
The restrictions on mine were choosing letters to make words and aligning them in the tiny window on the machine. I downloaded an embroidery design software, the free version and I can align letters and transfer that onto a thumb drive and put that into my machine.
Do I love it? Yes, and I need to find more ways to use it. Any questions just ask.
