You didn't say exactly, what delay sound you are after, more digital or more analog vintage.
If you are looking for the more analog delay sound, the Artec Delay is a good pedal to look into.
The Boss DD-6 is a very good digital delay IMO, but it costs a lot more.
The Digitech X-Delay is quite good for its price, I enjoy mine a lot, especially the slapback echo and the tape delay setting. It's kinda a jack-of-all-trades; other pedals do it better but are more expensive.
The Marshall Echohead is rather new, it might be over your price range but it has some cool features I like (like being able to choose between true bypass and spillover/buffered bypass).
