Muddy Fox Alu Lite

[Heavy]

I've got this MF Alu-Lite which has a snapped drive-side chain-stay near the BB. It came covered in XT, Hope & X-Lite so I'm guessing it was one of their better models? Possibly made by someone else?

I won't use the bike, so my question is: is it worth repairing? (there is a local alloy welder who is apparently reasonably priced, and the repair would be behind the chain-set.
