Not posting this to the DIY forum to hopefully get more opinions. I've been planning a new HT for some time, and I had originally planned on a Servo-15. But after being mostly successful at building a couple of front projector screens, I'm feel very "Bob the Builder"-ish, and after some great help from the folks on the DIY forum, I feel like I could actually manage to build a sealed Tempest. The problem is that after I get the tools necessary, some of the DIY savings will be eaten up. So when the savings started to diminish, I realized that I should once again consider the Servo-15. So it begs the question: what would be better for music and movies: the Servo-15, or a Bessel alignment sealed Tempest? Or would they be similar? Thanks! Martin.
