what is the height and length measurement of the throat of the juki 2010Q? I've found it is several places on the net but it doesn't say what the throat size is.

I bought the Janome Horizon 7700(they now have upgraded that to 8900) because or the 11" harp space to allow more ease in machine quilting.

I bought my Viking Sapphire 830 at the local sewing center as a new to me it is 10 inches and can handle any size quilt thought the largest I have dine is 120 x 120 inches (do quilts come much bigger than that?) :)

I was in the market for a machine with a 9" throat a couple years ago. I think the Brother 1500 had just come out and I couldn't find it for less than a thousand dollars. After going to every dealer and shop in town I figured I'd never be able to afford such a nice machine. Then I met Raquel. She is a 1954 Singer 66. Her throat measures 9 inches wide and 6 inches tall. She's a dream to quilt on. I've never been so satisfied with my machine quilting. I haven't started FMQ on her yet, but I did start piecing on her so I can get used to where her 1/4" is. I got her as a Mother's Day gift and the machine, all the attachments, & walking foot was less than 250.00.

I have the Juki 2010 and I love it. I have it on a grace start frame. it has a 9" throat and the height is close to 7"
It is a work horse I got mine from sewingmachinesplus.com I think this is the web very nice people to work with

I'm not sure what your budget is or how long of a machine your frame will allow, but have you looked in to Bailey machines? They are workhorses and have a strong following. http://www.baileyssewingcenter.com/test.html
