Drake, I must agree with vangor - please keep in mind that the project members are doing their work for free. And I really appreciate this, and their effort to improve the module. If you're not satisfied with it, I'm sure there are some commercial event modules available.
I cannot confirm that the module is "full of bugs". It works well for my purposes, except of one issue with the list view (causing an "Object reference not set to an instance of an object" error message). I posted a workaround here. Sure, there are some other problems reported, but in my opinion not more than usual - "usual" for any DNN module, or even any piece of software (free or commercial) I know.
The other error message you describe - "Sorry events are currently unavailbe" - I have not seen so far. Under what circumstances does it occur? Can you reproduce it, or does it occur randomly? If you can give a step-by-step description how to reproduce, I'm sure the project team is willing to fix it.
A word to "where the beta testers stoned?": I did a bit of beta testing for Events 3.3.7 (not stoned), but as I did it in my free time, I couldn't test everything (Sorry for my lazyness). Perhaps you'd like to support the beta testing next time (for version 3.3.9 or 4.0)?
