Brother makes a quilting/sewing machine with a larger throat - maybe 8 - 9 inches - for about $200. It is computerized so you also get a variety of stitches, if you like fancy stitches. You can usually find it in Walmart, and it is likely that it is also sold on Amazon. I like Brother machines; I think I get a lot of bang for the buck, so to speak.
One thing that is very important to me is the quality of their user documentation, and the Brother machines that I have had have excellent user guides.
Have fun shopping.
