I'm sorry but the point still stands: excellent idea but the price gap is way too big with themeforest themes compared to the benefits. 50 bucks is the max I would set aside for this, and I consider it to be a lot.
I donno, Modulz looks well designed and built. I like the professional feel it provides. Hiring designer to build something similar would cost a lot more than 99 bucks. It's not that much to spend for someone who's serious about their startup and want something other than standard themeforst/bootstrap. (That is until everybody starts using this, I suppose by then there might be a lot more versions/tweaks).
