StandALONe??

Im gonna be buying a standalone pretty soon and i wanted to know what your opinions were on this. I am leaning towards Hondata or DFI but i have heard good things about the APEX and i kind of like that display that comes with it. But im pretty sure on the long run these units work alike as long as it is tuned properly on the dyno. HOndata seems to be the easiest and cheapest out of the bunch but i have heard from a guy who claims to drive a 10 second car that he had it and it sucked. So i want to know what you peoples have to say. Thanks. Peace.
