What amp are you using? I have a Fulldrive that sounds fantastic in front of my AC30, but I don't particularly care for it in front of my Mesa/Boogie F-50. Find some place with a return policy so you can try it out for a few days and take it back if you don't like it.
I REALLY like my TC Electronic Stereo Chorus + Flanger pedal (think Eric Johnson cleans) but its not for everyone.
There are loads of good options out there for digital delays. I have a Boss DD-5 (love it, check ebay for them), Boss DD-20's are nice (but more expensive), Line 6 DL4 Delay Modeler (loads of options, good sounds), TC Electronic Nova Delay is nice as well. Check these out on youtube, and go plug in and try some! A lot of boutique pedal makers have some really cool delays as well but they're harder to find in a store (to try out) and are usually more expensive.
As for all-in-ones (I've heard MANY mixed reviews on this, but here's my experience) I've been using a Vox Tonelab for about 5 years now and have nothing but good things to say about it. My only problem with it is a switch went out... they sent me the new one in a week, I popped it in and was back up and running. I traveled throughout south america for 7 months with this thing thrown in my suitcase and still no problems. Its built heavy-duty and can take a few gigs a week for years.
