Now that I am on a computer, I will write more information on what I'd like!

As you all probably know, 90% of my vaping time is spent on an ego aio or my subvod c. The remaining 10% is split up into using a spinner (4%), the hohm skillet (5%) and the Smok M80+ (1%). So I think it's best for me to stay on the tube style devices. I LOVE the ego aio, but am not impressed with its battery life. I am a little spoiled after getting a provari for only $20, so I'd appreciate suggestions for devices with removable batteries that cost less than $40. I don't need anything high end. I also don't care what color it is. Pink is always nice, but I wouldn't care if I was tootling on a puke green device. Just as long as it works well for me

As an aside, last night I started getting dizzy off of my 18 mg nic, so I think it's time to go down to 12-16mgs. Unfortunately, I have made enough 18 mg juice to last a year. I was thinking of just making non-nic versions of all the juice I have and adding it to the 18 mg to lower it (or should I make lower versions due to differing steep times?), but I am not exactly sure how much to add to lessen the nic amount. I'd greatly appreciate suggestions.
As always, thanks very much for your help, I just love my new vaping family!
