I have the Egnater Mod 50 head, i think it's amazing!
The Egnater stuff is built better than the Randall stuff though and does sound better, but of course, comes at the higher price. My main module is the 'Erect' (dual rec) module. Which i asked for some of the fizzy mids to be taken out of. It has a brilliant high gain sound, better than my old 2 channel dual rec actually!
There are quite a few people that mod the modules too. To make them sound/look better/different.
The only thing is, is that you;re going to end up owning all the modules, like everybody does, haha! £££
