$325 does seem like a lot to spend on a pretty basic wheelset for a conversion. if i were you, i'd take that $130 you'd be spending on an eno hub, and put it towards a new entry-level track frame. there are a few to be had for around $200. then, you can buy any cheapo wheelset you want ($150 for formula hubs and decent rims), and build from there. that puts you around $350 for a frame and wheelset, instead of wheelset alone, and it doesn't involve ripping apart a perfectly good c'dale road bike.
