I was shocked that TFA’s recommended kit was $155! When did Raspberry Pi’s get so pricey?
The latest, overpowered version with all the accessories is that pricey. But you can do for much cheaper. For example: https://www.canakit.com/raspberry-pi-3-model-b-plus-basic-ki... Add a MicroSD card (if you don't already have one) and a case (if you need one) and you get to ~$75. You can do even cheaper by getting a $15 Pi Zero 2 W and an Ethernet adapter off AliExpress.

All can be bought for around $100 and are upgradeable with standard parts AND are multiple times more powerful than any raspberry pi.
