i started with a 510 pcc kit and quickly found the battery life wasnt working for home, so i got 900 ego for home and use the starter kit when im not. all i buy now is juice(and just cut the cost of that doin diy) and fluxo's. stock up when i need to and get enough for free shipping(not going to go to waste) a fluxo lasts 3-4wks(rotating 2 diff with 2 diff flavors) and broke even a while back. i dont need the newest space aged thingymabob to be happy. was smoking the cheyanne baby cigars at $20 or so a week and have still broke even.
