Actually, Slaw, I was responding to Cedar's post- where he described a DIY ultrasonic rig as a way of saving money. My post added an additional point- that there was a benefit to the DIY, in my estimation, over and above the commercial ultrasonics. That had nothing to do with you or your preferred methods. I'm sorry I got you upset over this. It was not my intention, and for those who know me on this board, I rarely engage in Internet sparring. Nobody is a 'bad guy,' and no one, in my estimation, needs absolution. Take it easy,
