The other option of course is to get the rebuildable deck for your baby beast? I've been eyeing one out on Vape Cartel's website for R180. I like the baby beast, and would be awesome to chuck some crazy builds in there and turn up the wattage!
But all the info available, you need to decide what you need from your vape, then look for things that suit that and your budget.
I was also considering this but not sure if I will need another device other then my al85 not quite sure what it can really do or if I will need another device that takes more batteries
