2B mods and N9 alphas may be my fav, or tied with original design.
Re alpha kit pricing: camping has Latin alphas at 62. Violet on cream had purple alphas (also numpad alphas) for 70, and that’s novelkeys pricing which is typically cheapest. Take away number row you could be in the 50s. Oblivion r2 sold over 1000 hagoromo alphas and was 55$.
