10 months ago I had also this dilema, Mediator
or G-Rex!
Go for Mediator! Maybe you should try to get
second hand one, if new is to expensive!
New is SX version i think. I have old 4 slot
version and I use 3 slots, so it's enough for me!
Mediator is very qualitative manufactured!
(Uf, I think I wrote this sentence wrong. Did I? :-D)
