Kanthal fused claptons are back in stock!
Just wanted to add, if you or anyone else are DIY inclined, wrapping fused claptons is actually pretty easy and fast, if you have a drill and what I call the Janky Jig

All you need is a bit of plywood, a few screws, a rubber tipped compressor inflator, and a .79 cent clamp from Harbor Frieght. You can also buy one here for $26, but where's the fun in that?

The trick is to make it as light as possible, so the whole contraption scoots backwards as you wind the wire. I used the really small clamp from HF. Two screws on the side keep the wood secured to the clamp, another screw in the middle gives the wire spool something to rotate on, the rubber thing is something I found to give a constant slight tension to the spool.
Here's a video of how it works...
...and some pics of the finished product. These are 25ga kanthal wrapped with 36ga nichrome80. 4mm inner diameter (!), 7 wraps. Only difference was how I set the jig up, to get the spacing. The non-spaced build is vastly superior, from the same tank. Since everything else about the coils were the same, that's proof enough for me as to how well claptons work!
