r3ality6KRO, not 20? That's very interesting. Because I've been wanting to ask if there might be anything at all different between this keyboard and the RF 104U Silenced from Elite Keyboards (temporarily out of stock but he told me more are due in in a few weeks). BTW, I read somewhere that the reason RF puts ABS spacebars on these is that PBT is prone to shrinkage, which is problematic with the length of the spacebar. Is that just being ignored in providing PBT spacebars?
key2manPBT is more expensive and difficult to mould than ABS. PBT might shrink during the manufacturing process(which can cause deformities in the material), but it doesn't shrink over time.
