I have no experience with the Singer Futura Quintet - have you tested one? Is there a dealer in your area? I have seen them on HSN and was very tempted but need someone local for questions.
My friend bought the Brother PE 770 and loves it. She can buy Disney designs from Disney at it takes a hoop up to 5 x 7.
I have the Viking Topaz 20 - I went to the dealer and got a great deal on a floor model so it came with the full warranty and they had lessons. My machine is an embroidery/sewing machine so in a pinch I can use it as a back-up to my Janome but so far have not done it, I use it for embroidery.
So check out the machine for yourself and make a decision because it is not a cheap machine and you want to be happy with your decision.
