Bridges on Matrix

I recently discovered that bridges exist on Matrix allowing you to communicate with others on different platforms.

I would love to make use of this, but I lack the technical abilities to spin up my own server… at least not without a step-by-step for noobs. Does anyone know of a server that's open to join that has bridges available to use? Or barring that some reasonably priced turnkey service? I saw one that was $22/mo for up to 50 users, but that seems a bit much for just me.
