Looking for a boxmod recommendation

Hi all,

I currently have a very close to dead iStick Pico 75w which takes a single 18650. I have loved this thing, and it's lasted since august last year but it's really on its last legs now. It's superglued together (the screw threading failed) and sometimes reboots on its own, but it's still hanging on damnit!

I am preparing for its inevitable death/explosion by thinking about what I can get to replace it. My preferences are as follows:

• Something small, preferably either single or dual 18650. Would much prefer 18650 style to integrated LiPo.
• Something capable of between 30-40 watts (I generally build my RDA around 0.6 ohms)
• Something able to survive a bit of abuse.
• Don't care about any special features, I don't do temp control or anything like that!
• Preferably on the cheaper side, I'm happy to wait for Fasttech seeing as my Pico is still holding out.

In the past I've had an Istick 20w, 30w, and the 50w, all of which were alright. Had a Smok M80 which was quite good but I was slightly afraid of it, and damn it was heavy. I also had an Aspire CF Sub which I loved until it fell apart. I'm a little out of date these days so would love for someone who's stayed up with the trend to give a rundown!
