At only $9.95, OrbitIRC is an inexpensive, powerful IRC client that excels at spicing up your IRC chatting experiences. Here's to hoping that the most recent release, v2.10, which was released in the middle of 1998, won't be the last for OrbitIRC.
Pros: Themes support, efficient and easy to use, excellent customization, inexpensive
Cons: Lacks real-time audio chat and other advanced features in ViRC and mIRC
