Incorrect, or at least misleading IMO.
The only reason you may have heard about things happening with the Marker line of AT bindings is because they've been out for a good long while now and are by far the most popular. FWIW I know a ton of people on them and most if not all agree they are great for what they are.
Conversely, I've heard a lot of issues with the Tracker/Guardian in the form of the aluminum rails breaking under odd circumstances, which is sketchy at best given their short time on the market. Some say they're fine, others say they broke while climbing on the first day, etc. Not something I'd want to be a guinea pig for tbh.
Also Barons are very close to Dukes in terms of durability so I do not understand where that is coming from. Also the F10s and F12s are lighter, stiffer, lower stacked and better hinged than the Barons and Dukes so there's always that too.
OP, I would absolutely recommend at your height weight to try to find a deal on some used marker AT bindings. Anything that will fit your boot and desired DIn range will be a decent way to start trying out some AT riding.
