Recommendations for inline 10G copper switch

Hello all,

I have been tasked to find a 48port switch that can do 10G copper without SFPs. I initially recommended 2 Cisco 9300UX and making a stack since those don't come in 48 port models. I got a reply that those are too expensive and to look into other options. I'm sure anything Cisco will be too expensive (even after a massive discount), so I was wondering if anyone had any recommendations.

I looked at extreme networks 5520-48T and not sure about it, but I am not familiar with Dell, Juniper, HP, or others unfortunately.

Any input is greatly appreciated.
