If you're talking about turning the fine tuner full turns and getting a picture each time, that's normal. Some fine tuners have a stopping point, some do not. If you watch the inside of the tuner as you turn the fine tuning knob, there's a cam that pushes a spring loaded pin in and out. That pin is what's making the fine tune adjustment. Once you go around the world once, it starts over again.

They seem to turn as one..I can hold the outside of the channel tuner knob...and then with other hand turn the center knob. Center knob does not seem to realy do much. So not sure if it is suppose to turn freely from eachother?

If the channel selector and the fine tuning are turning together, it could be a few things... the shafts could be slightly bent, the shafts could use a shot of spray in there to loosen old grease between the two shafts, or the knobs themselves are rubbin against each other. Seems I recall my HaloLite has a shaft issue as well. It's even worse with the chassis inside the cabinet. It's as if they didn't give quite enough shaft length for the knobs to fit on there well. They could have also designed the knobs a little better.
As far as modulators go, I don't think it matters too much. I have several, and they all seem to perform the same. Haven't bought one in a while, but i would think you could get one at WalMart or Rat Shack for 20 bucks.
