The problem with double shots is that until quite recently, they were always made of ABS. That means they get shiny, and generally (but not always) feel kinda cheap. PBT and POM have much better feel and don't pick up a shine, but double-shot PBT has always been a low-yield process. Recently a process has been developed to use POM for the inserts and PBT for the key body, and this seems to work, though the wrinkles are still being ironed out. Also, PBT tends to warp while cooling, making the yield low for spacebars. Lots of PBT-key sets still come with an ABS spacebar for this reason.
Pad printing is also not the only option. Dye sublimation is an option for PBT (it doesn't work well on ABS), and although it has less contrast and sharpness than double-shot, it does not wear out because it's not on the surface, it's in the first 0.2 mm or so. Then there's lasering of the legends, which is exactly what it sounds like. The uppermost layer is lasered away, and the plastic below is either photosensitive or is a different color. The downside is that contrast is typically poor and there is a derpression at the legend which can sometimes be felt -- the opposite of pad printing, where sometimes the raised area can be felt, particularly when a clearcoat is applied to reduce wear.
You're rocking a board with Cherry MX switches. There are plenty of replacement key sets available for you. The bad news is that the keys alone probably cost more than your entire keyboard.
