A great PDF creator program for free

I recently got hired for a position that requires me to create PDF's on a daily basis.  A couple of years ago I installed PDF Creator, a free PDF creation program.  It filled my immediate requirement, it was free.  I didn't use it much, but started to use it this week.  Well, it stinks.  For whatever reason, it is overly complicated and keeps crashing (crashes on two different computers, so it's not me).  I could go to Adobe Acrobat, but a couple of hundred dollars doesn't sit well with me.  After a couple of minutes of googling, I came up with CutePDF.  It's free and it works...you're hired!
