I have been watching reviews about the steam deck for weeks now and finally dedided to get one, I found a guy selling one with 512g on marketplace for $300. I play my switch on handheld mode a lot. I also have friends that play Diablo and I play fall guys TF2 and other computer games so a deck will be more convenient to play on the couch. Is there anything you guys recommend or that I should know before I buy it? Thanks
