Sewing Machines ? I don't know what one to get?

Erm well im gonna be needing one as textiles takes my life im not sure what one to get. I want it to be able to do quilting, twin needle, free machine embroidery, sew through jeans, decorative stitches etc. I don't want it to cost over �300. Or could anyone recommend me a good brand. I quite like Bernina Arista sewing machines as i use them at school. Thanks :) xxx
