buy cheap butterfly tenergy alternatives or substitutes.

I thought I would start a new page to give a new heading to group what it would seem is a very common thread of discussion about table tennis equipment.  What is the cheap substitute or alternative for tenergy table tennis rubbers?

I always wonder how much cheaper when I see this thread, and also how much less consistancy, spin or speed ratio to the original do you want to go?

I will add links here probably to all the tenergy substitutes or alternatives I got suckered into believing but I don't know if I will ever get around to trialling every substitute out there.  It's just to expensive.
