It's easy to get a PS5 I got mine first try off Amazon.Yes exactly. The microadjustments you have to do with the 30fps and what feels like input lag.
Feels much more responsive with 60 fps.
Honestly, time spent searching for a PS5 vs what your time is worth vs time actually playing games (esp if it's a hobby) just pay an extra 100 quid and get it off Ebay (I will go against the herd here). My mate spent countless hours trying to get one. Gave in and hasnt looked back.
Alternatively, have the notifications on the members market a few have come up for retail price and most will honour any warranty claims.
