Question- I'm going to get take the plunge into clipless and I've decided on these shoes - http://revolutioncycles.com/product/...es-52667-1.htm
(thanks to catnap for the blog article)

My next question is, it seems there's a few different pedal options for me such as SPD or platform (possibly DX also?). I'm a total noob when it comes to clipless setups, so what should I go with? Differences between them? Bonus points for giving me a link to pedals that will work good but are under 70$(ish)
