Depends on how cheap you go. "Disposable" phones aren't going to be comfortable to use, but you can get much better value for your money with a Chinese phone that failed on the international market and is massively discounted one year after launch.

My current phone cost 1/6 of the new Pixel but has more than 1/6 of the hardware. My only hard requirement was support for LineageOS 15.1, which is already somewhat of a quality filter because no volunteer is going to support a phone that's too shitty to use.
