I replaced my Rossi boots that I bought new in 1984 a couple of years ago. Like you, I was sad to see the comfortable old ones go!
I bought a pair of Fly brand boots for around $200 or so. They seemed to have no flex at all in them when I first got 'em, but over time they have loosened up a bit to the point where I'm pretty happy with them. The finish and general appearance has held up well, and they can certainly deflect logs, errant foot rests etc.
As a cheaper brand, I am very happy with them.
