You probably know already that Steam Deck LCD is on sale right now but people are also mass selling it which resulted in a huge price drop of used Decks. It’s doable to get a used 64gb for almost half the price of the new 512 OLED version. I believe soon after OLED hype fades away used SD LCD price will increase considering it’s not that much worse than the new OLED version. *IMO
I have the 512 GB classic Steamdeck and frankly I would not switch. Hell I wouldn’t even buy an OLES deck now, given that you can get the 512 GB for less then 400€
