Hi Pat. Virtually of the presses on Ebay are of Chinese origin. Due to high freight charges, they are imported in container quantities and are sold on an 'as available' basis. Basically that means when the container is emptied another one is imported, but not necessarily of the same make or model.
The build quality can vary considerably between the items on offer, with sharp edges and badly aligned labels being the norm. Having said that, I use one myself, which I won via an auction format at a very good price. Even though it is well built, I know that if it goes wrong it will be a throwaway item, as it would be highly unlikely I'd be able to get replacement parts for it.
As a cheap option they are ok, but you have to appreciate the lifespan of the lesser made models could literally be as little as a few weeks. You have to balance out the low cost against the longetivity.
Hope this helps.
