I've got a DM-100 on the way after stupidly giving one away a few years ago. Does anyone have one? I'd be interested to hear your opinions on how it rates compared to the DM-2 or DM-3 or even the CE-2 (it has a limited chorus function - you can't use both delay and chorus).
I've been using mine a lot for recording. The sound is captivating, almost hypnotic at times. It certainly compares favorably with tape delays.
It does appear to be a relatively rare unit - the only one I've seen on Australian eBay was the one I bought.
It's similar to the DM-2 but it does have a longer delay time and an added filter on the repeats (the Roland FCF - Frequency Controlled Filter - I'd be interested to know exactly how this works).
As for the RX-100, there seem to be mixed opinions. A friend of mine sold one recently for a hefty price - probably well over what's worth - so I'd be cautious and only go for one if it's good value.
