U can custom make one...
I made one for under $100... About $140 when you add in new oil..
Basically, any oil cooler will work as long as you can mount it up to the bike. All you need is the bypass spring which is bolted where the oil filter goes... That costs about $8. Then you can buy a used cooler off ebay for anywhere from $50-100.

and a write-up that I did back in the day.... Lists the parts needed... I used one off an M750
http://www.ducatimonsterforum.org/index.php?topic=25434.0Had I done it again, I would of had the oil cooler ceramic coated black(I made mistake of spray painting) and not have painted the oil cooler lines/connectors since they scratched..
I have since re-painted some things, but It still doesnt look as clean as I would of liked...
You could also buy a new oil cooler that mounts differently if you want.
