Yes the curl probe should meet your needs.
The expect argument should be fine for what you want although I seem to
recall it may also match the headers not just the body.

The sample config I have is

*** Probes ***
+ Curl
# probe-specific variables
binary = /usr/local/bin/curl
step = 60
pings = 5
forks = 10
offset = 50%
timeout = 5
# a default for this target-specific variable
urlformat = http://%host%/

*** Targets ***

+ WEB
probe = Curl
menu = Web
title = Web (http)

++ TESTSITE
menu = Test website
title = test.site.co.uk via curl
host = test.site.net
expect = Hello world
urlformat = http://%host%/wordpress/?p=1



Hope thats useful
