My choice is definetely the Zoom 707 Effect processor.
I was told it had some real cruel effects, and nice sound
and it was cheap and blabla.
Well it had effects, so far so good.
But all of the 100 or so effects sounds like
crap. The normal (clear, tone or whatever its called)sound
is the worst I've ever heard.
Its like playing a 500 year old rusty banjo while someone
is strangling a cat at the same time.
So 200$ for 100 effects that sounds terrible isnt good.
Its better to spend that on like 3 effects that sound good.
Now I havent tested that much fx-processors, but Im sure this is one of the worst.
