I had a set of Razo Magnesium pedals and while the brackets are a bit tricky to get installed properly, they never gave me any problems. As long as you make sure to tighten the bolts that hold them on every once in a while they will stay put just fine. Usually you can get a set of them for like 30-40 bucks or so from most online stores.
Some starting points to look at stuff:
Razo
Momo
Sparco
That should provide plenty of choices.
