what looping tool?

["martin daws" <thepoetmd@hotmail.com>]

i'm about to enter the loops. could you please advise me as to which 
looping 
tool(s) will work well for me. this is the spec:
i want to perform spoken word poetry accompanied with improvised vocal 
loops. for example, i sing a 4 bar bass loop, then i want this to 
continuein 
time looping seamlessly (assuming i've hit it on time) while i add a vocal 
hi hat. once i've got a few loops working i'll perform the poem live over 
the top. the effect i want to generate is of a track growing organically 
in 
real time, so everything drops in from the live recording without any 
stops 
and starts.
i was looking at a boss RC50 - what d'you think?
