I was turned down for Sedo Pro, and Sedo Plain's traffic just didn't seem right.
I mean, I have over 600 domains, even if they were crappy names, statistically, people falling on their keyboards should have produced more hits than sedo was accounting for!
My first few weeks with ND most of my domains that had sat with the "parked?" link at sedo now had traffic and hits. Its a shame that I waited so long to try them, because many re-regs are coming up.
A couple of points:
You will get more .02 clicks at ND, but you will also get .30 plus.
I think sedo does some kind of averaging, because I got many .10 clicks on domains that are .02 at ND. However, I get 1.00++ on some domains that were IMO averaged down to .10.
I use the overall average to compare. ND is at .10 and sedo hovers around .075.
I also like the folder organization at ND.
