is there a noticeable difference in quality of tone? i'm just looking for something simple, don't need more than 800ms, don't need reverse or other goofy tricks. which brand analog delay are recomened. i've read good reviews of the maxon and the ibanez (used $150 +/-, most affordable). the ehx only has 300ms, and the other one (stereo) is too expensive.

DD6 or DD20 is good. PLENTY of delay. Sounds nice. Its Boss's best pedal.

Its all preference. its not like tube and ss (where most go for tube). Bands use a lot of stuff becuase they're good for different things. U2 used both analog and digital. radiohead uses digital and so on

Digital sounds more clean and goes well with other effects
Analog is warmer and more natural but doesn't blend as well
