I think Torin just buys their stuff from the same factory in China as HF and a lot of similar products selling for about the same price on eBay. I wouldn't be surprised one bit if there are multiple companies all using the exact same design with the exact same specs being built in the exact same way on an assembly line set up exactly the same as every other company. I could be wrong but I think there are factories in China that send out lists of what they build to any company that wants to sell them. Theses Chinese companies only want to deal in bulk. I'm also guessing that they will make changes to their designs if a customer is willing to pay for it and willing to buy a large enough lot but most don't make any changes (other than paint color) and decals.
