$5 is a good price but I think John's storage scope is the type for use with a
terminal monitor, one that has no display. The 503 is a regular cart type. Dependant
upon what he wants and needs he'll have to decide. If I'm not mistaken the rack
units are as heavy as the ogic analyzers I had some time back last spring, about 50
lbs or more.The 503 should be about 30 lbs and is local.
