How to choose a balancing machine?

Is it worth spending money on expensive balancing devices if budget options do the same job? I constantly see ads for high-end models, but are there real benefits to using these devices? Maybe it's better to save money and buy something simpler?

I've used both expensive and budget vibration analyzers, and honestly, I didn't notice significant advantages of the expensive models. Budget counterparts work just as well and cost much less. I don't understand why the market inflates prices for vibration analyzers so much.
