Things to look for and consider:
1) how close are you to a dealer?
2) what's the routine maintenance expenses?
3) do you like the dealer? Does their registered repair guy have a good reputation?
4) Does the dealer include classes?
Really think about what you plan to do with the embroidery function.
I only ask because my dh surprised me one year with a DSE. What a sweet hubby. But I very seldom use the embroidery function and I have to relearn how to do it everytime. I find the changing threads so annoying. But that's just me.
