I've just seen this. I had ego batteries and used vivi novas to get more vapour, then I got a mod. I now have variable wattage and voltage, one battery lasts me all day (almost) and I can choose the vapour teperature and quantity by changing volts or watts. My Lavatube is plain old variable volts, the only difference between that and a sinner is a bigger battery and volts go from 3 to 6. The Vamo is now used much more with watts. It adjusts for atty resistance so you get the same power, it gives power in a different way if you want (RMS) and you can get the best performance from it. True that it is a little large, especially if you use a 18650 battery, but you can take the extension tube off and use a 18350, less battery life but a lot shorter.
Another advantage of any mod over a spinner is that when the battery dies that's all you replace, don't have to chuck the lot.
Some modders sell mechanical and vv mods here and some of those are cheaper than a spinner.
I'd also at least use a vivi nova atty, or a kanger, If you feel brave and don't mind a bit of a learning curve you could try a rebuildable atty, but probably that's best left until you have more experience.
