I don't own a Mediator and at the moment (until I repair my A4000 M/B) and I won't buy it for now.
But it's in my plans, and since the Elbox guys provided this functionality, it's a good point in their favour (they are still working on "classic" Amiga hardware).
Well, they may be more fair about posting real benchmarks and tech info about their products (like Individual Computers does), but it's very good about their commitment on the Amiga side.
So thumbs up for Elbox!

P.S. Elbox guys, if you are here, post some tech info and comments about this: this will improve your image among potential costumers, and probably higher sales.
