Ongoing subscription? – PDF Pro - Reader Editor Forms Review

I haven't tried the version 3 update. I use this as my primary PDF app, though I have to edit in others. I'd like to be able to edit in this but I don't like ongoing automatically renewing charges. Sell this to us once and the leave us alone. You're not doing any ongoing maintenance on our documents or anything. Don't be greedy!
