This thread is a bit old
I finally found the Dicain on eBay a couple weeks back from the distributor (no longer a registered user now though) and purchased it. I love the OEM look to it as opposed to Ownuser which is a bit bulky and well, not so great looking as you mentioned Pete. The Dicain grip is a solid quality product and it works great - makes vertical shots a whole lot easier. It comes with a wired remote which is a great addition as well.
FYI, Mike, the Dicain doesn't make a grip for the K series, but Ownuser did come out with one a while ago. Haven't really looked into it recently since I already have my grip.
