The SKYLINE series is a line of Janome machines. They are deigned and made by Janome.. If you go to Janome.Com you can compare their machines......the newest Janome machine is the 9400 MSRP $4900, the Skyline 7 MSRP Is $2900 (you can find specials for both).
The 9400 has 2.75 inch wider throat and more decorative stitches than the Skyline 7. The Skyline 7, like the 9400, comes with software to design your own decorative stithes, auto foot lift, pivot feature, advanced needle threader, just incredible features.....all the same as the 9400, for $2000 less than their newest machine....if the decorative stitches and 2.75" extra space is worth $2000...and some sewists do, then go for the 9400.
