What I really dislike in phpld is - frequent and common error of "invalid url" in most submissions. They ask to validate the url even if it is already good and validated.
I prefer eSyndicat over phpld.
I've never ONCE had that problem and I've been using phpld for a few years now (since before they started offering a paid version )
I suggest going with phpld, and what is it 25$? I would go with the latest version
