+1 Waves H-Delay. The only delay I use, but only for basic doubling, not chorus or flanging.
Same here, though I probably use it a bit more for delay FX. In fact, I like all of the Waves H-Series, and could probably get along with just a DAW's stock plugins and the H-Series (H-Delay, H-Comp, H-EQ and H-Reverb) -- an incredible set, especially if you can pick them up on sale.
That said, I remember just a few years ago Soundtoys EchoBoy was the delay that always won in all the popularity polls. That may still be the case. Of course, if you're like me, it's overkill for the simple delay tasks I need it for.
