I've been trying Parked.com out with some of my higher traffic names, and I'm pretty happy so far! In the week they've been there, they've made nearly as much as they did at SedoPro within a month. I've been a little disappointed with the click adjustments the next day, but I realize that's just the way it works, and that NameDrive does the same thing.

Just as an aside, I've got an incredible domain right now at SedoPro which I wouldn't even test out anywhere else for fear of messing with a formula that's really working right now: in the past three days, it's made $35.00, $36.00, and $47.00, respectively! And that's on traffic of about 200 uniques per day. Prior to that, it had been making about $3.00 per day (still very nice, of course). Anyway, I imagine this is just a major spike that will return to previous levels, but still, wow! And even cooler, I just regged it myself about 6 weeks ago. (And no, it's NOT for sale.)
