I am reading this with a bit of interest and confusion and I don't want to instigate the wrath of the moderators but Dave makes it clear on page 1 that this is not a crowdfunder. He is being commissioned by DTOS. So - this isn't quite the same as a crowdfunder - where the customer is taking on the risk of the venture directly with the designer and supplier (Dave) and thus cutting out the 'middle' man.
But what we have here is DTOS taking no apparent financial risks at all on this project, not spending any money on shelf space but placing itself as the sole point of orders and sales on behalf of DJModels.
I don't see this retailer is commissioning the APT in the same way as Hattons - which has for example put its own money up front for the RHTT models.
Beyond releasing Dave from the distractions of running the order books I would like to know what 'value' DTOS is providing to this project - if they are not putting any money into it but just pushing prices up by ***%, then it is no wonder the N gauge project isn't getting off the ground?
