Hello!
Appicient.com - Brandable and short, but only valuable if developed, imo. It's not very easy to remember. I would say low $xx.
MarketPhD.com - There are a few good sales of names ending with "phd". However, I don't see that "market" and "phd" go very well together. I would say mid $xx.
StockPhD.com - Same as above.
Best of luck!
