Seems that seller sells both KBC and K-Force, depending. Sounds like you got KBC which are perfectly good quality. KBC does not have a lot of texture on their abs, but that is not necessarily bad. I am 99% sure that WASD keys are the same source as KBC as both have identical mold stamps, texture and color choice (though WASD does not yet offer all of them).
As for waiting to get a good board before doubleshots... thats not a good idea. Especially if you want Cherry. The longer you wait, the more 'rare' and expensive they will get. Cherry is already out of production for 3+ years and new sets are already fetching premiums over $100. Often used too depending on keys.
