Pingdom Speed Test with Website Grader
I found tools.pingdom.com to be very cool as it shows you how long it took your site to load, what slowed things down, and gives you a grade. The best part is its free.
Vallue Add On Membership Site Tool
I was using Digital Access Pass (protection and processing), Wistia (videos), and Optimizepress (theme) to create a membership site. Using those three tools I put out $624 a year or $52 a month. The tool I found is $197 for the first year and $37 a month after your first year. There are no bandwidth limits (like Wistia), and I can create a website in minutes.
Who Needs That Many Details
Using Optimizepress the good news is you can control everything. The bad news is you can control everything. In many cases there are features that I'm just not using. When I watched the video for this tool I was amazed and they have great features I will be using such as:  

Progress bars as people go through your content (looks alot like Udemy)
Integrates with Facebook groups
Super easy merchant account through Stripe and JVZoo
No limits on videos and bandwidth. The videos are converted for multiple formats and html5 complaint so people can consume content on their iPads/iPhones, etc.
Great looking user interface with the ability for students to take notes in each lesson that are saved on the site.
I love that I don't have to worry about plugins, and my site's speed. It's all handled by ValueAddon
Valueaddon is co-owned by JVZoo which is a HUGE Affiliate network (so I know its not going anywhere)
So far the support has been quick and helpful.
You can allow downloads or not of videos and other materials

Here is a video of me showing the before and after.
