Other Tonearms that use Graham mount?

I have a Raven One turntable that is currently in storage that I’m toying with the idea of setting up in a second system) or selling but I have no idea what they’re worth these days.

The table came with a the original copper arm board that was made for graham. Later versions of the table had an interchangeable mount, but mine Is solid metal (which may actually sound better?)

Are there any other arms I can mount, other than Graham? (I moved my Phantom II to another table)

I’m not looking to spend much money on an arm since it would be In a Modest system, which I know a Raven One is way overkill for. I know there are all sorts of reasonable arms on the market.
