For those arguing about the price point, MKC sells a 60% case for $180 (http://www.geekkeys.com/mkc-aluminum-poker-case-silver/). That means that what this keyboard is dropping for is probably a fraction of what it would retail for. I am not saying that it is worth it considering other options, but that if you did want this particular board you may not find a better price. Also for those complaining about the lack of PBT keys, I would argue that stock keys are of similar quality regardless of material.
i.e. a well crafted set of ABS keys have a much better feeling than a stock set of PBT. Material doesn't indicate quality.
SygaldryAside from the fact that high quality ABS will probably not come stock, it is material science that determines which material shows wear faster, not manufacturing quality.
ImpendingDoomGMK and SP are like opposite ends of the spectrum when it comes to the quality of ABS keycaps. SP even specified that they made their keycaps extra thin to remain competitive in pricing.
