Looking to get a Catalyst

I am somewhat a beginner to media servers, but have taken courses on the Green Hippo and soon the grandMA console. I am looking to possibly purchase a Catalyst to rent out and also run with some local bands.

I was curious if this unit for sale is a good deal?

Thanks in advance!
Best,
