I like my Park stand that I got as a Christmas gift a few years ago. I wasn’t completely satisfied with centering/dish and messed with it a bit. I mostly messed things up until I got one of those centering gauges to get it back to good enough. I say good enough now in what others point out as the mechanical limitations of it.
I also realized that it is close enough for my riding and my bikes. I flip the wheels back and forth as I approach final adjustments and if I am close to 1mm, I am happy enough. I don’t do any high speeds, and I’m sure my 40-50 year old bikes are off by that amount somewhere anyhow. It is a very fun tool for wheel building and ease of use in my opinion for my purposes.
