Anytime I have had such a requirement, it has never turned into actually buying a tap device. Specifically for 1G copper we just SPAN the port. A small 8 port switch with a copper and SFP uplink port with SPAN/port mirroring capabilities are usually cheap. Then you can have 6 links for example to it and SPAN them at will without a trip to site to re-patch anything. Similarly we needed to mirror some 10G ports once but only had servers with 1G ports in those remote DCs, we just used a R-SPAN (GRE tunnel) back to another DC. You might need to elaborate on your requirements more. The only requirement we have had for an actual "tap" device is for passive fiber taps on more than 1Gbps (so 10Gbps, as 1G ports are just so cheap these days).
