Does anyone know a cheap alternative other than YBCO? Hopefully, temperature also doesn't need to be that cold and pressure is not needed. Any advice
is helpful.

In addition to the materials contained within, cuprate superconductors are generally difficult to make because they are formally Cu3+ compounds (hence
"cuprate"). No non-cuprate bulk superconductor works above the boiling point of liquid nitrogen without thousands of atmospheres of pressure.
The easiest superconductors to make with the highest transition temperatures seem to be the 122 iron arsenides:
