I pre-ordered the BlockRockit so I got it for $2600.00. I already have a Grace Queen frame so it will fit perfectly. It has all the features of a long arm machine and has a stitch regulator built into it if you choose to use it. It will be shipping at the end of this week. It was designed by Lynn Barlow and his wife so it has all the features of a long arm but with an affordable price. There is more info on it on their website:
