mihlbach is right here...they make a TON of different pedals in all variety of qualities. I've been using some branded as Forte for I don't even know how many years now and they still just keep on going (for the record, they are a LOOK Delta cleat pedal...not SPD). I also use a pair of Wellgo's branded as Ritchey on my mountain bike....Think I stuck them on there in 2008-ish...and they were actually used when I did.
My own personal experience with other pedals...LOOK's are basically indestructible, but can be expensive. I wore out a pair of eggbeaters (the bearings) in two months once. And I've never had good luck with Speedplays either.
And that ends my 2cents.
