I went straight to Prusa, which mostly protects me from my own ignorance and gives me way more confidence to actually learn and experiment with different materials, it’s worth every penny, haven’t looked back. YMMV. I too destroyed my Ender’s bed with inexperience. More than once. Being cheap, I suppose that’s why it isn’t such a tragedy. The other option is to just replace the print bed and carry on. I went through about 3 before I gave up on Ender. Still on my first Prusa Satin sheet 3 years later. I flip it occasionally just to even out any wear and tear.
