I am not trying to cast aspersions on you personally, but the terms warrant a lot of caution. You are relatively new to the community, you are not offering real escrow, and the minimum bid is MUCH lower than what other MR are going for. That last part is counter-intuitive, but is a hallmark of many scams in the past.
I think you can bury all doubt by simply agreeing to full escrow through John K., to be released on physical delivery. It really is that simple.
If I sold the units today with delivery risk factored into the price (i.e. discounted), but I couldn't get paid until the delivery risk was eliminated (i.e. unit in hand), how does that make sense?
If I came to this forum in 3 weeks upon delivery with 3 x MR500's for sale, they'd likely go for 300-500BTC each. I'm not asking for a delivered market price. I am asking for the buyer to assume delivery risk in return for a selling price substantially below market price.
Would it make more sense for me to offer this deal 2 ways? Full price for 100% escrow and discounted price for current terms?
I would think that some people would want to assume delivery risk for a discounted price.
I could care less about escrow or whatever. Before you getting my hard earned money, we are going to talk and I plan to do my own due diligence on you which will require probably talking to a lawyer in your area. So I guess if you're not comfortable with being fully open with this community, you're not going to get anywhere.
