Any of the various brands will fit, the only thing that is different is that you need the larger 'corse' size cup washer and nut as the shaft is larger than the 916/999 bikes. I have a JHP slipper clutch in my bike but it is the same as Bucci and other 6 ramp ball bearing designs. I bought it from another Ducati forum used for £200 ($400) and it cost me about £20 ($40) for the nut and washer.
The original clutch nut is very tight (250nm) and needs a 19mm hex socket to loosen it along with the correct clutch tool to hold the drum and basket.
If you change it yourself make sure that you stack the clutch plates in a different order to original, on a slipper clutch a friction plate goes in first NOT a steel like the original clutch.
I changed my clutch over in about 30 minutes.
