Just look for yourself.
50-60 hours a year. Not really a lot but I don't know your financial situation. If it's ok I would take the job without a doubt.
If your financial situation is like a lot of us (paying interest of 800-1000 euro a month) and your making less than that with this job I would reject it.
But maybe you could work parttime somewhere else to cover this.
To summarize:
It's experience. Although it's not a lot it's better than staying home flying those 3 hours a year VFR.
