I wasn't aware of the situation with DZ's auction, but I skimmed the thread and I can verify that you really are using this loan to pay for those items mentioned. I'll tell you what, in the event that Dz changes his mind and end up not selling the items, you can make a repayment of only 1.45btc. If he does sell the items to you, then in two weeks you can make repayment of 1.60btc, again no hassle of escrow or collateral required. Seems like a win-win-win for all that's involved if the latter plays out: I get the small interest, you get the items rare items at well below market price, and Dz gets his funds for his wedding/honeymoon.
In the event that you have a hard time paying back the loan in btc, I can accept fiat via paypal at today's market rate on LBC. I can be quite flexible for legit loans to trusted members.
