Vouch for Dieze. Sold him 7b 07, I went first, no issues as to be expected with Dieze. A flawless trader, highly knowledgable on what he's doing, and above all, highly recommended. Nice doing business!
Another major vouch for Dieze, sold him 6b 07 with me going first, payment followed swiftly. Dieze is in my book the best gold trader I've ever seen, it's an art to see him in action. Highly recommended!
