I've been with EKA for over 5 years and I've had some really good jobs from them. They have a good team of agents and I've never had any problems with them. I was also dubious about the charge at first, but they do have a professional studio where they do your shots and compared with a photographers fees £25 isn't so bad! They have always worked hard on my behalf and they call with jobs (rather than some agencies who will text and ask you to call them!) and after the first 2 yrs with them I was more than happy to pay another £99 for their admin charges because I like the way they work & I'd had so many good jobs from them. From my point of view they've always been well worth the money but I guess it's up to you!
