>Do you have to change coils
Occasionally when they start getting nasty, but generally a set of coils will last 2 weeks to a month before I change them. If I'm building with Kanthal, usually a quick dry burn and a brushing will remove all the gunk. If I'm working with Nickel, the entire coil need to be junked and rebuilt.
I used tanks with pre-built coil heads for a while, and they're convenient, but it's and extra expense and I don't like the idea of them eventually becoming discontinued or not readily available if my local shops stop selling them.
Building my own, I only go through about $10 in materials every 6 months, and I never have to worry about being caught without a coil.

>this will be the last mod you ever NEED to buy
But temperature control is a pretty compelling reason to upgrade though. Never getting a dry hit again - and sensing when the cotton is dry and refusing to fire… I'd consider it a necessity, but it's still too new, so there's not many devices that support it. The ones that do tend to be in the 100 ~ 150 watt range.

You should take >>3334 's advise. The istick 30w is a good choice on the cheap. Though if you're willing to spend a bit more, I'd just go for the IPV Mini II. It has a lot more wiggle room for experimenting with different builds and power levels later on if you decide to. You'll also have to buy a set of batteries (one to use and one to charge), but it's nice not to have to be tethered to a USB if your battery starts running low.
