I use one but it is a Delmhorst and was about $60 on ebay new. I typically turn the foot area down to about ¾ inch or less since it is side grain and not endgrain. Not a problem pushing the pins in 3/8” but they do sell an optional cable assembly to read without using the pins. I have never been able to find the pin holes after finish turning.
Not sure if the HF $10 is good or not. It would be nice if they had more reviews.
