Waiting for it to drop below 17 may be like "Waiting for Godot".
I put my order in a while back for $17.09 and just squeaked in. Check the return, check the FED and recognize that past history isn;'t quite the accurate indicator. It dropped by over $1 after divy annoucemnts and it probably isn't going to do much more than that.
If you have this in a tax deferred account the interest return will be just fine even if it takes a little dip regardless of fluctuations in share price.
