I'm a big fan of RasPis, but people _always_ understate the real costs. That TPLink wifi router comes in a case with a (probably shitty but working) power supply and cable, and inbuilt flash memory. A Pi Zero costs ten quid, but you need to add a case, a power supply, and a micro SD Card. But worst for me, is that they still limit you to buying one at a time, so if your decide "Hell yeah! 5 room wi-fi streamed audio sounds _Awesome!_" You're not only up for fifty quid for the Pi Zeros, but you're gonna spend at something like twice that much again for 5 half-decent power supplies, USB cables for the power supplies, SD cards, and cases, and then you're up for 5 lots of shipping charges because they aren't allowed to sell you 5 Pi Zeros in one order... All of a sudden that "fifty quid project!" has become a £150+ one in five seperate deliveries... (And unless you don't care too much about the audio quality, both the Pi Zero and the TPLink router will need a better external DAC anyway...) If you just want one, and you're the sort of person who has usb power supplies, cables, sd cards kicking around doing nothing, and you're not too fussed about having a nice case, sure, you can just order one ten quid Pi Zero plus 3 quid for shipping.
