Okay,here are a few varieties of what I think you are seeking:
Rebuildable Atomizers
and here, great processing time with these guys,
aga t 2 genesis rebuildable atomizer with extra parts
or are you just looking for the internals?
If so here:
Mod Parts
you'll find five different sizes of silica wick (CHEEEP) and a bunch of Kanthal and NiChrome, plus some SS mesh.
And here:
Wick & Wire
More wire and a couple of types of SS mesh.
The absolute most affordable wire of all gauges imaginable can be found on Ebay, though. Temco sells it cheap by the 100' and there's a guy who sells like 30ft sections also. Just do a search for "Nichrome"
Cheers
I was more looking for a "one-kit" just what someone may need for 3 rebuilds of SS(different mesh) and 3 rebuilds of Silica(different widths) and 3 different types of resistance wire capable of 3 builds each (2 for each SS&Silica + 1 extra for mistakes) gage. Maybe even Throw in some ribbon wire to make the set even more perfect.
