Hey man...sorry I didn't see this message/question sooner. The black Kluson style tuners are cheapies which I think may be Wilkinson. I had to use a little foil around the bushing to make it snug in the headstock because I didn't want to bore any wood out to use a larger bushing. Anyway, as inexpensive as they were I have had no issues with tuning instability so they work for me so far.
Here is the item on eBay from the same seller I bought from:
