I have the Eventide Time and Mod factors. Pricey but fabulous! If you have an iPad you might want to look at Eventide's new H9- controllable by the iPad and you can download all of the Eventide pedals into it, plus it has a few of its own. I'm thinking about it myself.
I use a Boss DD20, which is great in the loop of the Renegade. 5 presets and very versatile delay pedal. They can be had for $120-140. Another killer unit for delays and chorus is the Rocktron Intellifex. It's a rack unit but used, they're cheap in price but not in sound.
