i would recommend the tsunami chorus, sounds heavenly,
i have the ce-2, its not really that strong, rather transparent but nice..
the h20 i heard that the footswitch always have problem
just try the tsunami for urself..
btw tsunami's price should be just nice
tsunami - price around 150-170, size slightly big, tone very nice
ce-2 - expensive but have high resale value and discontinued, tone not bad, got vintage mojo, wont spoil fast or wont spoil at all
h2o - slightly expensive, not really high resale value, footswitch open have problems..
