Depends on your use case. Ex lease mini desktop Dell/Hp/Lenovo Intel machines off eBay can be good, and first class Linux support, and cheaper than raspberry pi. Some applications can be replaced with a microcontroller like esp32 which has excellent software support. Many of the machines above have pretty average Linux support but it seems to be improving, depends on your application.
