70$ before shipping and import taxes is really rough. I mean I will definitely order 1 set, but I can't help with more.
The thing is at this price we won't get any orders from newcomers. The veterans will surely place some orders, but then we will cruise around 100 orders just like in Ivan's GBs
My suggestion is to start the GB with your last kit at 70$, see how it goes and then probably fall back to a Mod Set Light.
I think the magic price for a TKL mod set is 49$ before shipping.
If it fails we should try a simple ANSI TKL set without Tsangan, ISO and whatever.
Sure we can't use it on our korean customs, but everyone of us also has a Filco, Ducky, KUL etc.
I'd rather have a standard TKL set that I can use with my vintage 10$ cherry sets than nothing GMK at all (again)
