I have a very similar version, cheap and works well. But no fancy features. https://www.amazon.com/dp/B07XQS8JL6/ref=cm_sw_r_apanp_svs6BKeeHL4tp
I use one like this. It's sold under a few different brand names. Mine was about $12 when I bought it. It works really well, and I'm not afraid of damaging it since it's relatively cheap. Not sure if this or something like it is available from retailers you have access to.

The weightman scale is actually still available, just not through that specific listing. I bought a different scale at first, but the weightman is way faster and a little cheaper than the one I had before. Here's the new link:

I’ve been using https://www.amazon.com/dp/B07XQS8JL6/ and it works nicely (with the cover pulled off), especially for the price.
Weightman came back in stock.
This works well for my gaggia and price is right. WEIGHTMAN Coffee Scale with Timer, 300 x 0.01g Digital Gram Scale with 600ml Silicone Bowl, Espresso Scale with LCD, Stainless Steels Travel Food Scale for Coffee Brewing, Battery Included https://www.amazon.com/dp/B07XQS8JL6/ref=cm_sw_r_cp_api_i_5F08Eb3ZHEFD1
Looks like https://www.amazon.com/dp/B07XQS8JL6 to me, I've had it for 5 months and no complaints given the price! I use it with a flair signature.
Not sure if the Pro X has a different drip tray, but I have this scale that fits great on my v5 and it has a timer function as well.
