With serious money at stake, the first thing to reassure yourself about is the diagnosis. Was the diagnosis of a catalytic converter failure on one bank of cylinders correct or could there be another issue causing the diagnostic code and engine fault lamp illumination? If the diagnosis wasn't produced by a Jaguar specialist, I'd be tempted to go for a second opinion before spending money on parts.

Assuming the diagnosis is correct, a second hand cat could be a sensible option but there simply isn't an easy way of checking it (other than visual checks for damage) before purchase so a second hand purchase does carry a risk. If a new aftermarket cat is a tempting proposition, why not ask how its spec (flow rate, quality & thickness of stainless steel) compares with the genuine Jaguar article before parting with your cash? If the supplier can't answer satisfactorily, draw your own conclusions! Mike.
