As a fairly new quilter, I think the hype of 391 stitches and 25 quilting stitches is overdone. I use 2 stitches - straight & zigzag. If I ever want to get into machine embroidery, I would look for a separate machine for that. I don't think that you need to invest in an expensive machine to enjoy the hobby. Also - looking at the space to the right of the needle, it is not that much bigger than many domestic sewing machines. From what I can gather, the 365 mm (~14 inches) is the length of the entire sewing space not that to the right of the needle.
If it is an affordable machine, you would probably have fun with it. I don't like it when ads claim a large quilting space, and then the truth of the measurement is merely a few inches different.
I do agree with the suggestion to test sew on multiple machines.
