Was like $46.99-47.99 new on Amazon yesterday. Fortunately if you want a new one, it’s $59.99. Amazon basics also sells a similar one for $22.
I had the Proteus which is a very similar corded one. It’s nice, but not for what I paid. And the rubbery stuff where your thumb goes always scraped off.
I have the G502 and it’s fantastic.
I just threw mine out a few days ago. I had it since 2014. I must have felt loaded at the time, because I paid $72 for it lol.
