As many have said, there are plenty of options. What are your goals with the delay? I've found that I prefer digital delay on bass, but analog on guitar. I like the crisp delays of digital for more ambient bass stuff, but shorter analog delays for guitar. I will say this, as well, though - when I tried analog delays on my bass, I preferred them brighter, and wasn't a huge fan of the Carbon Copy. I spent a good amount of time A/Bing my friend's Carbon Copy to my Echo Puss (both are analog), and the Echo Puss was a clear winner for me. It has a nice tone knob as well, so it could go both brighter and darker than the Carbon Copy. When it was all said and done, however, I've found that for my relatively basic delay needs on bass, an old DOD Digital Delay does it for me no problem. No reason to spend more money than you need, so I'd say the first step is to figure out what your tone goals are and go from there.
On a related topic, if you're wanting a short, dark, lo-fi(ish) delay, you might try some reverb pedals. Just figured out I really like reverb!
