I dono... I'm behind on posting sample pics, but I kinda like the SFX effect because it's more subtle and the film's cheaper than the alternatives and otherwise very well-behaved.

If you want a Konica replacement, it's probably Efke IR820c, although even that's not exactly like Konica 750. But it's a fine-grained film with loads of IR sensitivity.

My personal fantasy would be a T-grain/Delta-grain/Sigma grained IR film. That would be fun. Not going to happen, but fun to dream about.

Oh, and Freestyle shipped my SFX 120 format film.
