keyclone's source is not open and it costs money... thereby motivating Solid ICE (me) to insure its quality (welcome to capitalism). it is also coming from a company that has been incorporated since 1998.

on top of that, you have regular access to the developer... fast, responsive customer support, and has been proven in-game (initially shadowbane in apr 2006).

if there were any problems, they would become instantly obvious in these forums. all major problems are dealt with asap.

and the last time i checked... viruses, trojans and keyloggers are closed source, have no customer support, come from unknown authors, and are free.

i tend to be extremely cautious of such binaries
