bit confused re: basic and bauhaus modifiers. Is bauhaus supplement for basic modifier? Should I buy both together or just one of the set is enough to complete TKL along with Alpha's? Can I just buy Alpha's set and Bauhaus text modifier to complete my TKL (cooler master novatouch TKL) keyboard?
ChirpiNo. You need Basic kit. As you've correctly said, the Bauhaus kit is a supplement to any of the modifiers kit.
Alpha and Basic. And Bauhaus which you seem to want.
