I liked mine OK but if I planned to keep a lip spoiler forever I definately get the bigger one from unlimited tuning.

Mine was smaller and not as cool, but was cheap and temporary until I found an 04 trunk and factory spoiler to get rid of my doggy door which I have now done.

 

If I were to ever change mine out for a lip I would get a real E46 M3 and no other. The Infiniti M and ebay ones both look like crap (IMO). They just don't fit right so when you get close it stands out.
