Is it worth repairing a Minolta XG-2 SLR Cam??

[DeadEnd]

I have the above cam given by a friend. But the film advance lever somehow got jammed. I think the cam body and the 50mm minolta lens need to have a good cleaning to clear of the fungus as well.

1) Where and how much will it cost to repair and cleaning of the cam and lens?

2) Is it worth getting it fixed?

Thanks!
