I've used Barnett plates in the past, but never in a Ducati because of the price.
They are well renownd tho'. If you order from the states, you'll probably pick up purchase tax over there 6% I think, and then VAT when the get here.
Check that your basket is not worn first though. Fitting new plates to a worn basket will only mean they get worn out quicker.
If the basket is shot, then I'd recommend fitting a 48T basket and plate kit from STM
