Al, I've tried a diffuser and honestly, in most situations, just bouncing the flash (assuming the ceiling is reasonably low and fairly reflective) works better for how I like things to look. Of course Tyll's diffuser is way more sophisticated than the one I use so his results are much better with it, mine still results in too much of a direct flash look. Still, there are situations which demand the use of a diffuser to avoid the brutal hot spot that any direct flash (on or off camera) is going to provide when you can't bounce. See if you can find one of the simple cap style diffusers and then play around with it to see what angle results in the best results.
