Thunderbolt 1 to USB 3.0 hub for 2011 iMac
I've been searching for a few days for a USB 3.0 hub I can connect to my mid 2011 iMac through the thunderbolt port. I'm surprised there are so few choices, and the choices there are, are expensive. Plus the choices there are have other connections that I don't need (or are obsolete), like esata, or firewire 800. I just need some USB 3.0 ports.
Has anyone found a decent hub?
Thanks in advance
iMac, macOS High Sierra (10.13.6), mid 2011
