The Ibanez AD-999 is basically the same as the Ibanez AD-202, but with less controls and options. I would recommend the AD-202 since it has modulation controls, wet/dry outs, mic/inst inputs, wet/dry blend, and in addition to delay it can do Doubling, Flanger, and Chorus. You can also tweak it to get a longer delay out of it. Basically with the modulation controls you can do anything from reverb to tremolo to whacked out delay. And for $150 its not much more than a DD-6, and worth it.
