I'm interested with the commodores GB, but I've heard the SA keycaps are very tight, is that true?
Never own SA keycaps before.
I haven't heard that - but there are not that many SA sets around.
SP DSA used to be very tight, but that was by design for industrial keyboards that sometimes get dropped, so the keycaps were tight so they didn't fall off. SP adjusted their manufacturing process for enthusiast DSA sets so they were not as tight.
SA I don't think would be used as much industrially, so I would imagine they would not be too tight.
