Teal Deer: You will be happy with the terp profile that comes through and would be a good fit for your concentrates, or at least the stuff I've seen you post about enjoying (CRX etc).
I really, really like the Innovape dual quartz coils, and I use it with an eleaf battery. They are hit and miss with inventory, and you have to ask for dual quartz coils, they have singles and will want to move their cotton wicked coils. The one you are looking for is a dark gunmetal color, with a purple logo. The coil and mouthpiece run about $25 and replacement coils are $5-$10 I think. They are 5/10 threaded but you'll need the adapter since the threads are shrouded, if that makes sense. My biggest issue is trying to put a sessions' worth of material into the coil. I don't like to reload when the coil is warm or hot, and if I don't smoke what's in there it will leak through the bottom. Always remove the coil from the battery and it's easy to clean with a needle to clear the draw hole and a qtip cut in half to clean up the threads at the battery connection.
The dual quartz coil heats up almost instantly, much quicker than cotton or ceramic coils, where other units take a while to heat the resin to combustion. You'll burn a coil starting out, that's why I buy three or four at a time. You also want to watch the wattage, since the coil heats so quickly. It won't burn, it will just be a giant hit of forehead sweat inducing goodness.
I've pretty much given up on finding a unit that I can load a decent amount of resin or wax or raw distillate into a tank, since most of those are specifically made for ejuice that is watery, not thick like oil or other concentrates.

This is not the brand but it's the same, found via quick google search. The intake hole is on the bottom, below the dual coils, they are close enough to the bottom that they don't leave anything left over, and the quartz gets red hot, which I think heats up the concentrate, melting it, pulling it down to the coil. I've never had to clean out a coil, just unclog it. I've also never, ever had a burned taste like I have had with other similar products. The hole sits in the middle but you can stick a needle clean through the bottom to clear it, something that isn't an option with other cartridges or coils or skillets that I have seen. Get the needle red hot, poke, blow, reload. Or, use a dab/honey straw to clear the unburned stuff at the bottom.
They have a store near park meadows and another one on broadway and hampden south of ACA. The location I went to a month ago had a few left and I bought them out, but they said they're popular. I can send one if they are out or if you aren't going to be up this way. Shoot me a pm if you want or I'll keep a blue and a pink one for you in place of a cigar.
edit- you want to ask for a 'dual coil skillet'
