My Opinion...No Pro is not worth the Money. If you are having problems with Basic, Pro is not going to fix those issues.
Pro gives you a few extra UP's which may help when looking for rare files. It will also give you a few extra Hosts when downloading.
I don't use LW anymore so I will leave it at that. I'm sure you'll get more opinions on this subject.
You may do a Forum Search and find a lot more Post's and Threads on this subject.
