Adapter for Thunderbolt Display to modern M1 Mac

I have an A1407 27" Thunderbolt display and I want to connect it to a M1 MacBook Pro. I see an Apple Thunderbolt 2 to 3 adapter (A1790, I think) at $50, wondering is there is something less pricey out there that does the job. Anyone know?

And while I am asking, can I use the magsafe power cable on the monitor to power the M1 with the newer magsafe?

This is kind of cable is one for which I wouldn’t go for anything cheaper, especially if you’re going to use it to connect a display.

The new magsafe on the ARM based Macs isn’t compatible with any of the older variants.

Agreed. Go with the Apple branded cable here.

As an aside, the Apple cable is also bidirectional (you can connect ab TB 1/2 device to a TB 3 port or a TB 3 device to a TB 1/2 port. Other similar cables are not.
