I recently bought 2 delays - an old Ibanez ADL from eBay and a new Maxon AD999.
The ADL was $80 and is basically the same pedal as its predecessor, the AD-9. It uses the same Panasonic chip as the AD-9,
the Boss DM-2, etc. (I think it's the same chip in both of those.)
I bought
the AD-999 new, ordering it through Ihsibashi in Japan. With shipping, the pedal cost me $224, which is about $125 less than they usually run in the US. It also arrived quicker than ordering through some US companies.
I'll be using the ADL for slapback, fattening delay (my amp doesn't have reverb), and the AD-999 for longer delays. They're both very nice sounding delays. They ADL is a bit warmer and more natural sounding, and the AD-999 has it's own sound, which is still very good, and of course it gets 900ms of delay.
I heard good things about the Short Timer, but I just couldn't find a digital delay that sounded like I wanted it to.
For $425 you can step up to the Diamond Memory Lane, but that was more than I wanted to spend, though it's supposed to be great. At some point I may send in my AD-999 to Analogman to see if he can do the expression pedal mods they do on the AD-900s. He thought they probably could, but hadn't tried one yet.
If you can live with the 300ms of delay that the classic analog delays have, then that's your best bet - look for an ADL or AD-9 or Delay Champ. If you need more, the AD-999 is a very nice choice, and ordering through Ishibashi is much cheaper than purchasing in the US.
