One flaw I've noticed in the cheap imports is their inability to hold something securely when you only want to apply light pressure. I had a fairly decent import that I bought 20 years ago... when you cranked it down hard, it was great, but if you just wanted to apply a little pressure (to avoid marring something fragile) there was too much play in the jaws and it wouldn't hold securely.
If I put the same thing in my Reed or Wilton, I can screw it down until the jaws just barely touch the piece and since there's no play in the dynamic jaw, everything is held securely but gently.
Since a good used Reed, Prentiss, or Parker can be had for the same cost as a new HF or other import, I just don't see any reason not to own one (or two, or five...)
The Wiltons are very nice too, but you need to get lucky to find one at a decent price.
