A lot of places sell refurbished
equipment, seems like that one just specializes in the sailing market.
Most "new"
gear is never functionally tested, so in a sense a
refurb is better than new because it has been tested, failed, cured, and retested again. If the
price difference is right and the warranty is still decent, it can be a great bargain.
If the warranty is really short, it can also mean the manufacturer knows they have a
turkey and that model shouldn't be bought at all, new or used.
