I got the stylish 52 liter top box by Givi and the two semi stylish E45 side bags. With mounting brackets all about $800.00
Seem to be very good quality and worth it to me. I will be touring and need lots of space.
I had a 45 liter top box by Givi for three years on an XT600 and abused it regularly, it was water proof and held up fine.
