Over the years, I think I've tried just about every vise out there, only to come back to the same three-- HMH, Regal and Dyna-King. I used the HMH more than the other two, swapping it out on rare occasion for the Regal or the DK when the urge hits.
If I had to narrow it down further, it would be the HMH first and foremost-- great folks and solid customer service --followed by the Dyna-King.
Then again, that's just me...
