Re:Comodo - $49 (Score 2, Informative)

I've tested the trial cert. in Netscape 4, Opera 5, MSIE 5, and mozilla. They've all worked just fine. It is currently installed on a live website, 28,000 hits, 4 days, no complaints. Now, they have changed their intermediate recently, things probably changed since your experience.

No limitations on the free cert. No strings attached. It does expire after 30 days, though.

There really is no reason a CA must charge hundreds of dollars for these things. Up until recently it has been monopoly pricing (Verisign *spit*)
