Here is what i'm thinking... Signature plastics is selling blank white PBT right now for $37 + shipping to get an 87-key TKL set. Thats not bad in itself, but I wonder if we couldn't get a better deal by ordering 25-27 less keys.
Pure owners might have the option of buying a 'pure mod set' that just includes the needed short shift and extra 1x1 for a small additional charge.
I don't have any experience running GBs either, so if this has a lot of interest and some is either willing to help me host it or host it themselves that'd be awesome.
