Didn't know that. Thanks!
But if I decide to move up to the $200+ range, then Faital HF204/206 would be part of the pool as well, which a few here appear to prefer over the B&C and older/titanium HF200.
Part of my interest in the Lase drivers, outside of monetary saving, is the "thrill" of potentially finding a hidden gem. It's just that I am too cheap to buy them just to try them.
