Mark, I have an sxk in the stash if you can’t find one.Thinking I'll pick up one more haku riviera rdta clone. I'm not seeing any of the sxk (the 3 I have now, 2 in use and one backup) around at a reasonable price, but I'm still seeing the yftk clones.
For anyone who likes high flavor squonk rdta, 0.3 - 0.5 ohm single coil (I user 0.35 ohm txp 26 kanthal), this is simply a sweet topper.
