From what I understand the Google Adwords Editor is by invite only. But I would like to hear reviews from people who have been invited to use it.
http://services.google.com/adwordseditor/?utm_campaign=ae&utm_source=us-em-invite3&utm_medium=email-invitation I just installed it and trying it out. Will let you know how it works.
I've been using it, and it's pretty good. I haven't added any campaigns lately with it but its easy to use. The spreadsheet is alittle tight. But its ok. I have over 150 campaigns running so it isn't that easy to go through them all but then again it isn't easy on the site either. I give it a thumbs up! No problems yet.
Does everything you need. I go back to the site for reporting, but its still beta. Nice not having to keep firefox open to adwords and autorefreshing. kdc
