Note that the Pi 5 is $60 (4GB), the case is $10, a good microSD card is $10, and the PSU is $12. So total to get into the Pi 5 game is $92, not $140. All of those things besides the Pi 5 itself right now are in stock at my local computer store, so no shipping either ;)
And Pi 4 is a perfectly reasonable computer for many, many use cases still, and is available practically everywhere again.
