It depends on your definition of cheap. I guess any Thunderbolt 4 dock would do, but I have two Book 360s hooked up to Plugable docks.

The first Pro 360 (mine) is connected to the Plugable UD-ULTCDL USB-C Triple Display Docking station (about $189) connecting to 3 1980 x 1080 monitors.This one has the capability to charge the laptop.

The second Pro 360 (spouse) is connected to a simple USB-C to USB-A hub that then connects to the the Plugable UD-3900 Dual Display Docking station (about $99 which then connects to two 1980 x 1080 monitors). This one does not have the capability to charge the laptop and I have it connected to its wall plug.

In either scenario, you have to download the Displayport drivers from their website and reboot the Pro 360 and viola.

But again, I guess any TB4 dock on Amazon can do the trick so long as it can do multiple monitors and have the necessary drivers.

Edit:

Upon looking at Amazon, This device is only $80 and looks like it can do what you want with two monitors. Just download the display port drivers and you should be good to go.
