Unfortunately the one thing that can't be controlled is time. Documentation is very time consuming especially when a piece of software like TNet is changing with every release.
As someone who has researched pretty much all of the competition out there, TNet has been by far the easiest to learn. The samples given in the example scenes give you quite a few different scenarios and best practices. They are also very well documented. Easy to learn from.
For the price, there isn't much better out there.
I wish you the best in your networking adventures.
