I have a Sapphire with the 10 in throat. Great machine. Use it for stitch in ditch and free motion borders.
I also have a Jane which is the same as the Brother 1500. Do not like it. It is set up on a frame with a stitch regulator.
Had to buy a strait stitch for the frame and regulator. It is a big hassle to use and wish I could afford a long arm machine for my frame. The biggest problem is having to walk around the frame alot just to turn the wheel to move the needle. Also have to move the machine to the end of the table to thread it since it has a very old fashioned threading with lots of turns and even one section that you put the thread thru a hole. I hate the under the machine bobbin case also much prefer drop ins.
Just bought a Brother xl2600 light weight for classes and it is a great little machine and inexpensive.
