My mom has one (I still have my 730) and she loves it - we actually haven't played with the embroidery much but plan on it as soon as time allows. One thought - they just came out with a new 7 series which I would really look at. Depending on what you are doing - the throat space is I believe only an inch shorter, the bobbin is even larger and stitches are very comparable. Pricing is I believe less. 710 sewing only, 750 sewing 750 E sewing & embroidery, 780 sewing & embroidery. In addition to the large throat area, larger bobbin these also have the even feed feature which is wonderful.
I am not affliated and only reason I know this much is I am considering selling my 730 and going for one of them. Probably the 750 without embroidery since the embroidery module from my mom's 830 will also work on it.
