@pauly - I am just going by what I have heard from dealers who sell both SS and tube equipment and many contributors to this forum, and from my brother in law who has had to replace tubes on multiple occasions because of problems in addition to having to install a fan to compensate for the excessive heat they radiate (also it was to rid his room of cigar smoke). I have listened to his system, which sounds very nice when the fan is turned off. I am sure he has spent several times what I have on his system, which is fine for him.
He ended up replacing the amp with a very expensive Conrad Johnson set up, but still uses the fan when needed, which of course detracts significantly from the optimal sound of the system.
Maybe he just had bad luck along with all the other posters who say they are problematic or at least needing care and feeding, but I think maybe you've just had good luck. He is still committed to tubes because he thinks they sound better without ever trying solid state.
