I started a thread in Ask FC for you because suggestions would be off-topic in the temperature thread. If you don't need discretion then I think your best framing hammer would be a Solo. If you want a pocket portable that you can use discreetly when you're out, then the Pinnacle Pro will do the job. As for tack hammers, I don't use pens for buds but from all I've read here the only one worth trying is the T-Vape, and it requires a bit of learning to get good results. The MFLB is an excellent and discreet pocket portable but temperature control is entirely done with breathing technique and battery contact time. You can learn how to achieve the temperature that works for you but of course there's no display.
