It's no secret the manufacturer is having trouble with the SP30. Unfortunately this is NOT uncommon. Look at what just happened with the S3 miners? Pre-order hashrates are subject to change, like it or not. Your ordering a product that DOES NOT EXIST yet.
I don't agree. If a company advertises in black and white to sell a product with specifications and price stated clearly, they have to honour that order. If they cannot due to manufacturer issues (between GAW and Spondoolies) this is not my problem at all. I expect a refund option or credit option for the difference in specification, from GAW, not Spondoolies. This is consumer law, as the contract of sale is between me and GAW.
