Agreed. I usually use them as-is until the burning taste gets overwhelming. Then I'll de-wick and they're good for a while longer. Then the crud gets too thick on the coil and they're trash for me. A 2Ω cisco usually goes 2 weeks then gets dewicked and is good for another week or two. This is an acceptable longevity to me for the price. Now if only I could get a rebuildable atty that works on the reo I'd be set.
One stock product I've seen that is really easy to get to the coil for rewinding are the Vortex (808/901 threads only) or Kanger G4/G5 (808/901/510 threads available). They are actually a horizontal clear bottom-fed fillerless carto, but with a REO I'm thinking the bottom feeder just might work with them, and you could even cut the carto into a shorty if you wanted.
The reason I mention this carto is because you can easily wiggle off the tubes and get to the coil. That coil pulls right out (no solder holding it in). With a nice pair of tweezers or tiny needle pliars it's not very hard to push a new one back in either.
NHaler does have a self/build atomizer kit, tho' I'm not sure that it would work well bottom fed. The reason I mention the kit however, is because they also carry nichrome wire and silica wicking material kits intended for that system, but of course you can use it to wind coils for other things as well.
