I was a member for a year. One thing to keep in mind is that the vast amount of work is based in Dublin. So if you live within commuting distance then it could be worth it. Also, the time when I got most calls was from about May until October. The rest of the year was pretty quiet. That was a few years back, so things may have changed in the mean time.
I’d reckon it was worth it if you had the time on your hands, as a matter of fact ( anecdote coming here )
If you’ve ever seen the silly ad with yerwan in the Kitchen and then in the bath on RTE .
( Y’know for hot water ? ) , She’s from West Cork , it was shot down there and she got the job from movieExtras. They seem sound enough .
