vocal effect unit for live gigs

anyone have one?

i need some thing for performing live, preferably all in one i guess

it's mainly for delay/ chorus / pitch up & pitched down vocals & combinations of different shit

rapping& singing

something with a pedal would be good i guess to just be able to kick it n keep going

suggestions

something by line6 maybe ? (their new stuff include xlr inputs and a looper)

a korg kaoss pad ?

My band's vocalist uses a boss VE-20.
It has a harmonizer which is interesting, and it has settings that make beat boxing sound cool. The presets are great on it. It is the same effects that are on many roland devices. Watch a you tube video of a woman named "singwithBetty boss ve-20" to see what it can do.
The ballad setting on this unit can make a person sound awesome. The VE-20 has a nice reverb and it has balanced outs, and a pitch corrector and a looper.
Actually I might as well add the you vid of it.
cheers,
Ian

oh sweet, cheers guys

i'm actually digging the look of that HD digital fx pedal, only $100 more & it seems to be packed full of fx for guitar & vocals

i'm not close to having the money for this before christmas but it's defiantly the next thing on the list
