With Gigabit Ethernet, there are only Ethernet Switches now -- no actual hubs, like there were for 100 Mbit/s Rthernet and 10Mbit/s Ethernet. But the "unmanaged" sort of switches essentially act just like hubs, for routine purposes.

I've had good results with the TP-Link TL-SG108 8-port metal-cased switch for around $20, though some Ham Radio operators say it has more HF-band RF noise than competitors.

My second pick for a metal-cased 8-port unmanaged switch today is the Zyxel GS108B. Like the TL-SG108, the GS108B is extremely power efficient and the newest revisions use a 5V input voltage instead of 9V, making them a bit easier to power with USB Type A if desired. This switch is also around $20, and it has the lights on the opposite side from the TL-SG108, but I don't have personal experience with it.

I have bought unmanaged TL-SG108 units, and I recommend them for being one of the two 8-port units I know with the smallest power consumption. Be aware that the newest revisions shifted from a 9V input to a 5V input, which isn't necessarily bad, but it means the power supplies aren't compatible, if you're looking for interchangeability. There are also reports that the TL-SG108 leaks EMI in the HF band, despite the metal case. I have powered the 9V version from USB Type A, and the 5V model will be rather more straightforward to power from USB Type A.

The netgear is fine, but undistinguished to me. I would suggest the second lowest power-consuming 8-port metal cased switch I know, the Zyxel GS108B. The current revision of this one is also 5V input.

The Cisco white unmanaged line is pretty new. At the current price of $58, this unit doesn't look bad -- it's not the cheapest for 8 ports of PoE, but I'd give it serious consideration. Loop Detection is a really nice feature to have in an unmanaged switch, because it should prevent the one major thing that can go wrong. However, in a home environment or one where you have control over the network, there's not much chance someone is going to loop up the switch while you're not paying attention, so I think Loop Detection is mostly of value in environments where there's some likelihood that non-engineers could plug things in.

But the other thing is that if you don't need PoE, you shouldn't buy a PoE switch. Why? The power bricks are huge, and even when there are no PoE devices, the switches use considerably more power, for the PoE capability. If you need PoE then that Cisco is attractive, but if you don't need PoE imminently, then I'm confident that you'll be happier with a non-PoE switch. It isn't a feature that's "free", because the power bricks are so large and the power consumption is so much higher than the couple of Watts of an unmanaged 8-port switch.
