I can't decide which model/ if I'm wasting money getting tons of features i don't need etc.

My local dealer will give me a great tradein value on my current machine..so i can get a
Quilt expression 2036 for $700
Quilt expression 2038 for $1000
or a display model (serviced) 2046 for $900
(I am stateside)
Anyone out there in a position to help mr choose?
