I have also used the DD5, DD3, and DD6 (digital delay pedals) in the past. I prefer the 1st two. I've also owned, and use the CH-1 (the blue chorus pedal).
Boss pedals are easy to modify, and because they're relatively cheap, you can probably do it yourself. Or, you can have someone else do it for you if you like the Boss
tones.

These guys seem to have a good handle on modding Boss pedals.
