I use Redline alloy pedals on both of my bikes (black not silver). Relatively cheap, like $10 bucks on Amazon or about $20 in the average LBS. (Ouch. Way to undercut the local guys Amazon.) There are pros/cons to discovering this.
Point being they have a great space for my feet, are rigid, yet comfortable - look bad a$$ on my touring/utility bikes and are sturdy as frick. Believe me I've tested them. 
You can get magnesium platform pedals for $60 but unless your beating your bike to heck you might not need to spend that much.
