WTB Light Tech bindings Ideally ATK

Helping a friend who has been a tele skier for a few decades pull together their first tech setup. The goal is to save some weight for an efficient touring setup.
Shes about 150 lbs so nothing super high release value. Budget is a bit tight so looking for a deal or lightly used.
Ideal setups would be an ATK binding Crest, Haute Route, ETC but would consider other options. A good deal on a pair of alpinists would be within range. I mainly want it to be a binding that I fully trust as she is heading on an icefields traverse up in Canada in April and I do not want to be responsible for a binding that malfunctions. Needs to be a little modern so nothing along the lines of speed turns.
Ordering a pair of Ski Trabs from Europe is on the table and around three hundred and ten so that is the benchmark we are trying to get under.
I also need some bindings in a similar vein so just let me know what you have.
