Out of the Egnater dual channel modules, probably the EG3/4; nice chewy tones in that one. You should also look at the Jaded Faith XTC (he can do a dual version). Salvation makes one as well.
Hmm. I have the EG3/4 and it's more of a Marshall sort of tone to me.
I have a Randall XTC and it sounds pretty awesome when you set the all of the controls around noon.
As said, Jaded Faith and Salvation have offerings for the tone your searching. I'm not sure if Hilly still has a modular rig, but you could always PM him and ask. I went with Sacred Groove my XTC tone. I'm not sure if he is currently taking orders.
