  We present Ho results from Cosmic Background Imager (CBI) observations of the
Sunyaev-Zel'dovich Effect (SZE) in 7 galaxy clusters, A85, A399, A401, A478,
A754, A1651, and A2597. These observations are part of a program to study a
complete, volume-limited sample of low-redshift (z<0.1), X-ray selected
clusters. Our focus on nearby objects allows us to study a well-defined,
orientation unbiased sample, minimizing systematic errors due to cluster
asphericity. We use density models derived from ROSAT imaging data and
temperature measurements from ASCA and BeppoSAX spectral observations. We
quantify in detail sources of error in our derivation of Ho, including
calibration of the CBI data, density and temperature models from the X-ray
data, Cosmic Microwave Background (CMB) primary anisotropy fluctuations, and
residuals from radio point source subtraction. From these 7 clusters we obtain
a result of Ho = 67^{+30}_{-18}, ^{+15}_{-6} km/s/Mpc for an unweighted sample
average. The respective quoted errors are random and systematic uncertainties
at 68% confidence. The dominant source of error is confusion from intrinsic
anisotropy fluctuations.
