**cough** All-round! **cough**
All-Round: the one company no one seems to know about. If I ever have the urge to ditch the pop-ups, I'd probably go with them. Reason: price, looks, and uniqueness. Just something else to think about.

Also, Ab-Flug produces the Grim Light kit. IMO, it is by far the best looking kit for the S13, but with it comes a price. Around $1,200 to be exact. The might be a rare find though, as I believe they are discontinued...
Other: R-Magic full bumber kit. This one replaces the front bumper, with a new light system that eliminates the pop-ups.
