When I started quilting 6 years ago I bought an Elna 7200, with a few accessories I didn't get much change out of a £1000, early last year I bought a Singer 527 and I adore it, it only cost me £50 and it does the most beautiful straight stitch and for FMQ it is the best, and I have 4, of the machines I have.
IMO save your money for more fabric and go for the reliable and well built Singer.
