Fun thing about the Resurrect-O-Nomitron is that it's not only a choice between between zombie or regular sim. If you pay almost nothing, nothing happens, you don't even get your sim back in zombie form. And if you pay too much for your sim to be a zombie, but too low to get a perfect resurrection, you will get something in-between. The resurrected sim's personality will invert, and they will suffer various other deficiencies too such as losing skill points depending on how much you paid. Their appearance is still the same as when they died.
