I recently had a batch of 20cm x 20cm flexible silicone heaters custom-made. Personally, I prefer these over the PCB heated beds. They are rated at 180W, have a built-in 100k thermistor, and 3M adhesive backing.

I’m selling for $30 each with free shipping in the US. If you’re outside the US, let me know, and I’ll try to quote you a price.
