The tyr are a great choice. I ski powerselect and they are quite light for an adjustable binding. THe free flex works great.
Like someone else said, I also like tyr because I have _never_ had them release when I didn't want them to, or fail to release when I did. I can't say the same about Markers, but of course YMMV. If indeed there is a warranty extnsion with them, you might consider it, but I bet you save enough on the try to outweight this.
Salomons have never appealed to me, but that's just personal preference.
