Hi, I have the H2O, like both sides. unfortunatly the echo side died on me and as I don't live in the US, the dealer has to send it out (not for two more weeks...) and then I'll have to wait for it to get fixed, wait for the shippment back... you get the picture. Anyway, I was thinking that maybe it is time to have a backup dely. I have known the DD3 for a long time and I know it an "OK" delay, reliable etc (never owned one). I also saw that new Carbon Copy. any suggestions or thoughts on which one should I buy? I'll do the search here on each of them and I'll try both in the store, but I was just interested to hear (read) what the guys here have to say... please chime in! thanks.
