In reply to Brent.

I don't think any of the quotes or comments were meant to demean the premium plugins. Many are indeed great.

The simple fact is that when I sat down to use them 2+ years ago now, there were lots of small issues with the PayPal plugins. Some bugs, and lots of things that simply could have been included but weren't. I haven't looked at their latest version. They could very well have added some of that, and I'm sure they've improved it overall in various ways.

We did indeed start with their plugin. As the article mentions I was originally going to simply extend their stuff and build off of it. It simply turned into stripping out all of the PayPal integration, replacing it with our PayPal class libraries, and then adding many new features from there.

I'm pretty sure you will find our plugin is vastly different from theirs at this point, but yes, of course we used whatever we could when we got started. That's one of the beautiful things about open source. :)
