Regardless of the juvenile exchange we all just witnessed, I concur that if you are still shopping there are caveats to avoid, BUT,,, Polo if you have it now, make the best of it for the time being, and use it to its fullest potential. In a few years, when you outgrow it, you may even resell it for vintage money.
What's the build quality like?
I ask because...
I happen to own an ASM Hydrasynth which is a subsidiary of Medeli, but distinct nonetheless, and the Hydra is built like a tank and very well supported with software and firmware updates.
Remember, there are 40 year old Casios out there fetching a king's ransom these days.
