The 4566 is a very well made, reliable and accurate boat anchor
I had a Lionheart LH9 (the domestic name that Daewoo is getting imported under) for a while. I liked it just fine, it was solid and accurate, but it didn't do anything that I couldn't do better with a surplus 5906. Still, if I wanted a "modern" 3rd Gen Smif I'd probably look them up again.
