Hi, the QNAP QSW-1208-8C has a mix of RJ45 and SFP+ ports; up to 12 can be in use at a time including up to 8 RJ45 ports.
From QNAP's website: "The 10GbE SFP+ ports are backward compatible with 1GbE SFP; the RJ45 (copper) combo port supports up to five speeds (10G/5G/2.5G/1G/100M)". It costs about £500 in the UK. It's an unmanaged switch. I've had one for a year, no problems with it so far. I've used Cisco, Aruba and QNAP transceivers in the SFP+ ports, it appears to be vendor agnostic for the SFPs.
