I'd got for the TP-Link TP-LINK TL-SG108E Managed Network Switch - 8-port for £30 from PCW, but this isn't a bad deal. You don't need a managed ("smart") switch for that, if you need to ask the question then this probably is overkill for you. You can use an £8 one for that.
This any good to run Xbox one through
I prefer to physically have a switch tbh, that was I can make use of it with some old machines I'm looking at getting
Don't think this will have the same CISCO CLI interface features. What's wrong with Packet Tracer or GNS3 ? Both are free and you can get plenty of labs by Paul Browning or David Bombal on Udemy.com for about £10 - £12 ( Price fluctuates on a daily basis)
Yes, especially for Sky Q hub owners with only 2 Ethernet ports :-)
