Ditto on the Fulltone or Demeter. I had a Fulltone for a week, but quickly returned it, after I realized I wasn't going to use it much. Now, if I need tremolo, I just dial up a good one on my Line 6 Blue pedal. I actually found a really cool way to manipulate the tremolo to decay and slow down, so it sounds like a Helicopter flying off in the distance. It turned out to be a much more interesting effect than a traditional tremolo.
