Im also going to say the AGA T2+ because...
*It's stainless steel, with a glass tank so any e-liquid is fine in it.
*IMO it's built like a brick sh*t house!
*Larger diameter overall makes it a bit less of a fiddle.
*You can experiment with mesh wick, silica wick and silica tube wick with mesh inside or (my own choice) silica wick inside.
*Comes with a bit of mesh and wire so you can at least have a go, as soon as it arrives.
*Costs around £20.
Just check what the vendor says about the glass tank though - the first ones had very rough edges and some sellers (I believe safercigs and cloud9) have got new glass tanks made with smooth edges.
Hope this helps.
