I have the Brother PQ1500 which is the Brother version of the Juki machine ( I believe),,,
....It has 9" space in the throat, a knee lifting,automatic threader and automatic thread cutter also has a big extension table....
...It makes straith stitch only and a great free motion stitch........I couldn't live without this machine.....
What I also love about it machine is that it keeps the fabric well pressed...(which the cheaper machines don't do)
I use cheaper machines for the decorative stitches when needed....on small projects.....
........ :D
