TC Flashback (has tape mode and analog mode), Echo Park (has tape mode and analog mode AND the amount of modulation is controllable, like the DMM.)
Personally, I had an Echo Park right beside a DMM, and as for the quality of the modulated delay sounds, the EP is every bit as good. The DMM does have a cool preamp in it that does something cool to the tone & feel, tho...
Personally, if you don't want to spend the bucks on the El Capistan, I think you'd be pretty happy with the Flashback or Echo Park, for half the price.
