I just got mine in the mail Saturday, and so far I really really like it. I was advised by board members to get the largest one that would fit, so that is what I did.
If I understand it correctly, they made it just to fit my machine. I think it said 3-5 weeks, and mine came in three weeks. It is an early birthday present.
I got mine from allbrands.com, and the thread that is mentioned earlier is mine... All the advice I got there was good. I have not yet quilted on it, but I am busily piecing on it quite happily. I bought it to quilt on, and the fact that I like it for piecing is a plus.
