Most shops that advertise screen replacement should be able to find a screen and do the job. You'll probably have to ask because these aren't common enough for them to advertise screen replacement services. I just bought a replacement screen for my HD 10 on eBay, shipped from Hong Kong. Expect parts to run $70-100 US. (July 2016). UPDATE: I ordered the screen yesterday, will update this thread when I get the part. Hopefully 10-14 days.
I am seeing replacement screen/digitizers for these now on ebay. With a little searching around I found one direct ship from Hong Kong for $70US. Good Luck!
