Don't care about %, want the cheapest one you got.
I can pay with some combination of gold badges, photon drops, and photon spheres, or maybe something else if you want but I don't know if I'd have your wants.
Bump. Still looking for one. Have around the following:
At least 176 PDs (may have more since I last updated this)
22 Eggs
2 Photon Spheres
4 Photon Crystal
And am willing to spend a lot of this to get a Heaven Punisher if I need to. But I really want to get one. You can even have stuff like V101 if you want it as part of my payment for it.
