I got a cheap RDA (squid clone) from fasttech, and I like it. I use it on my iTaste VV V3.0.
My thoughts:
I like dripping when I want to taste the "real flavor" of something. It does produce much better flavor and vapor than the clearos I use, however it is really not that convenient, even at home.
Even though mine's rebuildable, I don't know if I will get into making coils yet, I'm sort of on the fence about it. So for now, I'm buying pre-wrapped coils. The dripper I have came with a wick and coil already installed, and I haven't had to change it yet (I've had it since December). I did re-wick it with cotton today and it's waaaayyyy better than the silica it came with.
I don't think it's necessary to get into rebuilding since the coils are available already. Sure if you want to 'fine-tune' to the Nth degree you can do that by rebuilding. But it's not like you're left with no choice if you don't feel like you're ready yet or want to deal with the hassle.
So far right now I am not dripping nearly as much as I am using my clearos due to the convenience factor, but I sure do like having the ability to drip if I feel like it.
