The 4000D limits you to using the smaller hoop. However you can rehoop some quilting designs to get a bigger design. I'm not certain what other machines are out there where you can use a 8x8 hoop; but the Brother Quatro has an 8 x8 hoop and one even larger. Also there are some great quilting designs built into this machine plus the ability to pivet and sew in multiple directions. You might want to take a look at itsince you have the 4000 they might give you a good deal. I traded my 4000D for the Quatro.
