I'd have my suspicions on the quality for that price for 1000. Seems almost too good to be true.
In my opinion the hooks are the most important piece of fishing kit you will use as it catches you the fish and bad quality hooks can result in many lost fish and fish of a lifetime etc. I would stick with kamasan or fulling mill. I bought hooks of ebay and never again, they bent in the vice when wrapping a thread body and then snapped when I tired to remove this bending.
For £20 you could 200 kamasan hooks and you will know that they are quality. Also I dont think its worth it to have soo many hooks unless you going to tie commercially. I tend to buy hooks as I need them, recently bought enough to fill all my boxes and now I have enough hooks left over to replace lost flies etc.
