I also like to mainly vape using temp control. And although I have tried Replay mode on the DNA devices I don't find myself using it that often. I already mentioned that I ordered a Dani Box 21700. That was done with money from the sale this weekend of a Rebel 250C squonker and a relatively new Paranormal.
I have two Dovpo Mono SQ. Last night I gently covered one of them and sent it to the holding drawer next to my desk. So right now my active toys are 2 - Original Billet Boxes (I sold 2 SXK clones last weekend), 2 - dotAIO, 1 - BMM TiNY v2.5 250C, 1 - Hippovape Kudos, 1 - Rebel dual 21700 250C, 1- Mono SQ 75C and last but not least 2 - Dani Box 21700.
Here's a comparison picture of the Mono SQ:

The Mono SQ is a nice size and functions well. But my actions answer your question. When the new Titan Dani Box arrives the second Mono SQ will be gently covered and stored.
If you finally decide that the Mono SQ is for you I know where a gently used one is available.
