>And that right there is why I usually stay out of these discussions. I'm too stupid for this stuff lol We each have our arenas of knowledge and capability that we can speak to as experts or at least credible sources of true information. This subject is where I shine and have a passion for. I can speak to much in the realms of solid state physics, electronic engineering and lasers so I get a bit crazy when these come up and I see something that needs correction. I can also do this in the arena of VCR repair, but that sadly doesn't come up much these days even though I still have that passion in me.
