I hear you, but if you wanted a pedal system and had the bodies already, these axles are what, $60. Yeah, you'd need the conversion kit and some odds and ends, but given that the system as a whole is pricey, it might not be a bad idea.
Personally, I love my spider based pm's. I'm on Time pedals so never considered a pedal pm, but people that I know that have the Rally's really like them, and they have a narrower q than the Assiomas.
