I know this is a niche purchase. It is certainly not for everyone.
We are individuals, and I know the resolution is unacceptable for the 4K heads. This is the cheapest I have seen with free delivery. They price-matched Scan it seems, but you have to pay delivery with them.
I also know people don't like Ebuyer, but I have personally not had a problem with them.
