Two things:
1: Whatever it can do can be done quite a bit less expensively in other ways that do not compromise the results.
2: Based upon my own very short tenure on this forum, there is no substitute for knowing quite a bit about what the heck you are doing, WAY beyond what you might get by skimming an alleged "step-by-step complete" instruction set from Shor or anyone else. And there's no shortcut to knowing what you are doing other than studying quite a bit. All that knowledge is here. Not knowing a lot of it means you'll almost certainly be running down blind alleys and wasting expensive chemicals and making decisions based upon "gold fever" and not clearly understanding what the limits of possibility are. If you are talking about Shor's $576 (last I checked) kit, that is 1/3 tr oz of gold, 10.3 grams. There are people in their beginning/learning stages who work long and hard over many months to get 10+ grams of gold. And you'd be surprised how much weight/volume of material will be needed to produce that amount of refined gold. I myself find I can sell gold-bearing chips for close enough to their potential gold yield on ebay to make it very clearly not worth it for me to get involved with chemicals, hazards, wastes, glassware, safety gear, not to mention the time and effort involved.
Your mileage may vary, of course.
