I'm the exact opposite. I LOVE to tinker, I love working with my hands, I love building stuff and putting things together.
I've played with the prebuilt mods and was left somewhat unimpressed with their results. Now I'm starting to want to get into mechanical mods and RBAs, not because I want a better experience vaping but simply because I would enjoy building a few.
I'm also the person who bought a brand new Mustang in 2011 and had it in my driveway all of about 3 hours before I was removing the interior to rewire the whole stereo system and install different speakers, a sub, and an amp. I've spent 20 hours doing a professional quality paint polish and detail on it before. I just like working with my hands.
But that's me, and I realize most people are not like me. I try to stay away from recommending mods and systems that require a lot of knowledge, effort, or complexities unless a person is specifically asking for that sort of thing. Not everyone wants to turn vaping into a part time job with lots of expenses and no pay.
