Rebuilding is definately a good way to go. I started rebuilding CE5's back in the day, but today, rebuilding is super easy compared to what it has been in the past. I'll go over some pro's and cons:
Pro's:
1) RTA's are the same price as the standard tanks, but the materials to make a coil are way lower in the long run, so it will pay for itself for the price of a few replacement coils from standard tanks.
2)You get the vape YOU want, not what they decide for you. Most tanks offer 2-4 different coil options for premade... with RTA's, it's whatever YOU want.
3) Flavor... I have never vaped a tank that was better than a RTA. Sure, there are plenty of premade coils that taste rpetty good.. but the RTA has always been better.
4) There for the long haul. I still have some RTA's that were released years ago... even though they don't make the atomizer anymore, It can still be rebuilt.
Cons:
1) learning curve. My first true RTA ended up being a projectile thrown off the back porch. Back when I started, It took me four hours to try to get two coils on a small deck... after multiple tries, I finally got it together.. then put some silica in (the wick of choice at the time), put some juice on the coils, put it together, filled it, then had the whole tank leak out the airflow.... It then became a projectile from the back porch. The next day, I found it and kept working on it... Luckily, todays RTA's aren't as hard as that one.
2) Higher initial startup costs. even though the tank is cheap, you'll need to buy your first wire, cotton, snips, screwdrivers and/or coiling jig, ohm meter, nail clips, scissors, etc. But if you get enough coil and cotton, you're set for an entire year.... I sitll have some wire I bought 2 years ago.
3) not as easily grab and go. Sometimes, it's easier to take a prebuilt coil for out and about just in case...at least until you get the hang of things.
For the atomizer, I suggest the Griffin RTA. The velocity style deck has taken hold by storm because of it's ease of use, build size, and leak resistant qualities. at one time I swore off hex grub screws due to them stripping, but those don't strip... I am back to using hex grub screws again.
here's one rebuild of a griffin to show you about what to expect. I wrap similar to what she uses... I just use less cotton in mine (my cotton doesn't go past the ring she puts on)
LOVE Zophie's reviews! She is down to earth, has an infectious enthusiasm, covers all the bases in her assessments and is downright easy on the eyes.
The Griffin looks great, and is certainly in line with what the OP is looking for. But it is very similar to many velocity style RTA's including the Boreas, Aromamizer, Gemini... so those should all be considered and compared.
Without knowing what mod the OP is using to fire it, I'm not sure if a dual or a single coil would suit her setup and vape style. For single coils, I love the Merlin.
