I have a Janome 6500 and Love it. BUT... I highly reccomend that you decide what is most important to you of what you want and need. Make a list, research online and then GO and VISIT local dealers. TEST DRIVE their machines.
They all have a different feel and what I like you may not and what you like I might not.
They have no problem letting you actually sew on their demo machines. When I was buying mine, it took me forever and I tried all kinds! Best idea I ever had! SO GO TEST SEWING! and have fun while do it!
