the G-Rex4000D is superrior to the Mediator because:
- it has a video-slot (u can use there an Arxon scandoubler which is full 24bit)
- it has cleaner software installation, u don't have to use tricks to install rtg drivers (because elbox never came to agreement with the p96 authors)
- it is faster than Mediator because of it's direct interface with the MKIII/CS-PPC
- can run MOS which is available NOW (any OS4 "advantage" the Mediator might have, which I seriously doubt, is only speculation, because we never know if OS4 will ever be released for classic amigas :-( )
- and a PERSONNAL advantage is that G-REX uses CGX and not P96 for RTG...
but as already has been said, Mediator is a good product too because
- it is available, sold and can be bought brand new NOW
- u can use it with whatever cpu card u have (g-rex needs MKIII or CS-PPC)
- u can buy (the rather expensive) Spider2.0 pci card and have USB2 on the amiga
Maybe Amigaz can tell us more, he has a Mediator4000D , which I hear from him that the 4000 versions of mediator are WAY better than their 1200 counterparts...
