Hi Harold/Group, been a while hope all is well.
Wondering about this item on eBay for $525. Called the "iShor Simplicity Scrap Gold Platinum Refining System" claims to refine to 99.95% for $1-2 per ounce with no nasty chems. I'm wondering if you think it's worth it or better building my own. Also, if it could be used for old computer chips, etc.
