Just to be clear... the second option you mentioned (Genesis Maxi) is not the same one that Dave Dorn broke on VTTV there appear to be two quite different beasts bein some in some places as a cobra copy. Actually the one from vapingthings is more like a clone of the genesis maxi (I posted a review of it on here in the reviews section). By all accounts it is ok, not great, but ok.
The Aga T is generally being very well received by many. If you want to use a silica wick Todd has done a vid to show you how:
You need to buy Kanthal Wire to wrap your coils out of - I would suggest you buy some 0.2 diameter for low resistance coils and 0.18 or 0.16 for wrapping slightly higher coils. I would also recommend you buy some wire mesh (400 gauge) as I am fairly confident you will want to try it after a time since most people who have these atties say that they perform better with a mesh wick
