This seems like a good deal:

INTEL 100SWE48QF2 Omni-Path 100Gb 48-Port Switch with Dual Power | eBay

I think these switches may be OPA-only (Omni-Path Architecture); Intel's proprietary 100G HPC fabric - So they may not speak Ethernet.

I haven't been able to get OmniPath AOCs working on ethernet switches either. I'd stay away.

They may also speak Belter, but yes probably not Ethernet.
