I played with the prototype in August at the Festival of Quilts in the UK. I succumbed and ordered it, and it just left the UK on its way to me this morning.
I don't have room for a big set up with the long frames etc., so I will have the benefit of the 16in harp, but will still move the quilt under the needle, just as with a domestic machine, except that this machine is mounted on the table so it faces you, rather than being sideways on as per domestic machines are. Another plus over a domestic that might be a little larger than average is that these are true long arms (but the smallest in the range) and can be updated at a later date with a frame etc., and they have the larger bobbins - these hold about 2.5 times more than a domestic machine.
Mine should be her on Tuesday - it's been hard having to wait this long, but I am nearly there now, and I have a lot of Project Linus quilts lined up to practice on.
