Nothing beats the DTv3 right now. And Matt will make the Quartz Cup right before he releases it. He's already pushed it back multiple times because they don't have it perfect yet but it should be within a week. I'll have a test model soon to report back.
Now back to the OP question. The reason the v3 is the best option right now is because rosin is dirty, so using coils just leads to many many constant ISO baths. ANd I HATE ISO baths, so I no longer need to do them. In fact, I rarely use ISO at all to clean my DTv3. Follow this guide and you'll be golden;

I keep the 3 base screws off so I can load directly on the donut. Then when I'm done a full session I can clean it up with a tissue so it's fking mint for the next session. I roll for months MONTHS on the same coil. I'll sometimes unscrew the base screws a bit, hold the donut down with a dab tool, and re-secure them. And it's OK to let the dish sit a bit loose, it can move a bit and still work great.
If you leave the house with it, just put the base screws in until you return.
The only time you'll need to do ISO cleaning or switch coils, is if you break a lead down in the post, which can happen if you do it too tight the first few times. Make it secure, not over tight.
to note I have the following devices all put through serious paces: CF-710, DTv3, SAI, DT-Gen2, PAX, Miracle S, Firebox, DBV, MFLB, BC globe, Omicron4, Yocan E+, Puffco+, Puffco Pro 2,Linx Hypnos Zero, Genie, Vapire Digital. I think that covers them all.
EDIT: almost forgot. The posts will fill up with reclaim, just leave it there, it doesn't affect anything. You cannot prevent it from seeping down there eventually so dont' fight it.
