You can get two Acuda S2 sheets for 48 euros (roughly 42 pounds) from the site above. Other than that, you can consider purchasing Friendship rubbers which are really, really cheap. Or you can use a chinese rubber on your FH and spend more on your BH tensor.
Personally I hate S2 alot. If it's tabletennis11 which u're going for I suggest Rakza 7 which IMO is way better than S2 but similar price. Even more spinny than your Tenergy(assuming yours is commercial version).
