Here's two: ATI Corporation - Tach-All(tm) Quick AttachMichigan Iron & Equipment: Kioti Dealer or try your Kioti dealer. I think the adapter for the fel arms is @ $350-375. There are attachment plates if needed to convert a standard hole mount bucket, etc. at @ $125-150. The plates require some welding to your standard attachments. As with everything, prices go up with time and these are a year old or so.
Another member from this forum had purchased the Kioti QA for his CK30 and said it was built well and he liked the set up. $300 plus shipping doesn't sound bad. Maybe that's the way to go.
