[Rails] recommended HTTP client?

In the past I have used Net::HTTP to call trivial remote services.
These calls have been low frequency so didn't bother looking into
alternatives.

I'm now looking at a design where I will be calling a remote service
that returns a simple CSV but it will be called frequently and if that
service goes down I need to degrade gracefully. I'd like to punt if
the web service fails to respond in 1 second (500 ms may be better).

Is there a library that makes this simple. Seems like some hackery is
needed to make this happen with Net::HTTP
ex: http://groups.google.com/group/chicagoruby/browse_thread/thread/8b8aadc26545e165

It seems like there are 100s of ruby http libraries out there.
