Master Replicas Limited Edition Lightsabers have been produces between 2002 and 2007 and are no longer comercially available.
The selling price was around 200$, but some of these sabers are worth a multiple of this price for collectors by now.
The hilts itself have no real function and are for display only. The size is movie accurate, which makes the sabers suited as an eye-catcher on every show-case.
