Nah. I think your guru is over-stating the problems, if they are decent 
CRT PJs. The setup on my 
Marquee CRT projector has not been touched in months... nearly a 
year, in fact, and running a pair of them is not that uncommon.

Setup on some of the older CRT PJ's takes a while, and is not as 
stable as mine. I can do a complete setup from scratch in about an 
hour, and it will remain that way for months.
