Don't ever pay for hacks.
That's what I say anyway.
Just wait for someone to release it or code your own hacks.
I make my own WarRock Private hacks in D3D every week, each hack takes me about 2 hours.
I never release public hacks because they will get detected and people just leech, a year ago I used to release a lot of hacks, but now I just try and help people in this forum and test hacks for people etc.
Good luck.
