just a suggestion to Geeetech company to sell every parts of "Delta Rostock mini G2s" such as motor mount, platform spider ( metal version) , metal dual hot end, etc or perhaps in metal -aluminum top/base plate ( I'm pretty sure you will have lots of customer interested not only the owner who bought your 3D printer but you will expand your customer ) so the previous owner will be updated version...these also applicable to other 3D model ..
I think these will be awesome ideas..
