I have the NV-1000 (older machine about 7 years old) and the 1500D (2-1/2yrs old).
Love BOTH of my machines!
Go for the LARGEST hoop size machine you can afford. Highly recommend this. That
is why I have both machines because in the end 5x7 wasn't big enough for me so I
got the 1500D with a 6x10 hoop.
Now I am going to be honest.............. 6x10 isn't big enough for me now!
