A RUNNING and RIDEABLE cb1000c should net you $1200- $1500 on average in the used market. That is enough to get you into a running 550 (which might feel a wee bit small if you are over 6 ft - shoot for a SOHC cb750 instead), albeit not a pretty one. As a junkpile that doesn't run and needs a fuck-ton of parts to make rideable your bike is worthless.
BTW rideable means new tires, cables, filters, oil, etc....basically safe to operate on the street.
