this is just IMO here.....
I got my first KPT a few months back. At first i unboxed and filled, not removing one of the top little "flavor wicks" that sits above the coil. It went dry on me a few times and i got harsh hits with little to no vapor. Then i removed the top wick and all was well for a few days. once the wick was saturated and dried a few times, i noticed i would get gurgley and it did flood a few times. So the next head was with both of the flavor wicks......again harsh dry hits and little vapor. So in the box of oldies it went.
recently i went back to it and tried to rebuild it with silica wick. Now it was fairly easy to do but it did not taste right to me. I am not a fan of the way most silica tastes. So after some digging here i found out a bout rebuilding the KPT with a micro coil and using cotton as the wick. cotton like a cotton ball or from the end of qtip. I had some wire lying around and gave it shot by following people's methods here on ecf. My FIRST micro coil was nothing short of amazing. The flavor was much better, plumes of vapor were being blown across my table and the throat hit was increased almost 2 fold.
I tell you this as you say you do not want to rebuild. If anyone knows me on ecf, they know i am carto tank lover. tried CE style for years and never was a fan and Genesis style to me sucks. So when the KPT came out i was like eh, lets try it. i like the design and the amount of juice it holds and it looks great on my chrome provari. Now with it working this well and being this cheap to not only buy, but to rebuild....its perfect for my style of vaping.
moral of the story, maybe try spending about 4 dollars on some 30 gauge kanthal A1 wire and use some cotton balls or qtips to make a wick and give it a shot. its not too hard and i would hate to have to offer you some $$ for the KPT. i too was there at almost giving up but it can be re-worked into what works best for me and maybe you too.

PS: and what people say about the heads getting gunked is 100% true. these coils are small and never evenly spaced, the wicks are tiny and the juice is always pulled on to them by gravity. i found that these heads get gunked a lot faster than any carto, clearo or any other device i have ever used and that goes with any juice IMO.
