Hi and welcome tricky, I've got some evods and they're great, especially on slim devices like egos, an alternative is the Protank Mini. I use larger mods now and use Kanger Protanks because they work well and I'm lazy, the larger tank size means I have to refill less!!
The Evods, Protank minis and Protanks are all good 'next step up' devices. They are reusable as the heads can be replaced, the
n when you become more confident you can learn how to recoil them and that makes it much cheaper.
There are alternatives that others may suggest, but I've not used tham so can't help with those.
