Not yet. The SR2 was my bread and butter for years. It bought the second machine. Now in order to increase production I am currently rebuilding my original machine that started it all from the ground up since it is unserviceable. I invest every dollar I make back into the process. Ironic, the profits of this batch went entirely into ONE 85lbs slab of steel for my new machine.
It took almost 2 years for me to build the second machine. The success of this block will defiantly help with the second build. This way I can do 2 batches at once. Like people are asking for the ASRockX11 blocks, but they are so complicated and time consuming. I will have a dedicated machine I can use for stuff like that, and my current machine for production runs like the Dark Blocks.
Either way, I am happy where things are going. I have come a long way in the few short years I have been doing this here.
