just try a noose or gun to the head instead of sedo...
there are a number of "other" parking options... but at the end of the day they are all using "your" domains to further their "business" yes the odd multi domained portfolio can make serious PP (parking profit) but there is nothing (at the mo!) that beats a developed, well generic coded, mini site / niche... website
even if you spend 6 months part time working on one project and get it right you will end up with more than you will "earn" from sedo... in a year!
