Here's an update.
Before Aug I was still speculating whether they were genuine and honest of fulfilling orders. Guess what, it was a surprise they really did it, and in fact was kind of shocking an old discontinued release was still obtainable thru the distributor and shipped to the warehouse. They showed me a few photos of the two models I asked them to order and put them side by side so the photos were indeed genuine and not doctored up. I then paid for both models and they shipped them via UPS SurePost.
Within a week the package with both models arrived safely. After this order, I started giving them some credits by placing another order with them. Like the first order, they didn't ask for a deposit or anything to special order, instead they ordered the models to arrive at the warehouse first, showed me the actual photos, I paid and then they shipped out.
I got the second order yesterday as well. So I guess they're coming for real at least for now. Also, looks like they're replying messages pretty fast thru their website's chat messenger. I don't need to contact them by email at all.
