For a person stopping smoking, the 20watt iStick is a great buy. Beginning Vaping, making the conversion from regular cigarettes, most people use a juice close to what brand they smoked. ie: Menthol, etc... However I'd buy the 30watt iStick. Due to the fact you'll find yourself wanting to sample premium Flavors. Which are going to require better Tanks, higher wattage. Like the other person said its worth the extra $10. This is only my opinion and my experience. I have graduated to the 30watt iStick with a Delta II Tank. I've only found one flavor that I can't Vape with outstanding taste with my current set up. Your cheap juices which you will start with, Will Vape at a low wattage. When your ready to flavor chase. You got pretty much all you need. If it were me starting over. I'd have bought the 30watt iStick, the Delta II tank straight up of the rip. At this time, I have no justification to move beyond what I have. Maybe add a Tank or two for quick flavor switching, with a nice tip. Your looking at $90-$120 depending on the prices in your area to start right. And be satisfied for a long time. Don't waste your money to regret and have to step up in your equipment. Do it right the first time, and you'll save in the long run. iStick 30watt is a excellent product. Again just my advice. It's your money. Best of luck. I'd like to see you happy Vaping. PS. the Delta II has a fluid control in the coil for the thinner cheaper, starter juices. I would not buy a Melo tank. I have one. It's low budget. Aspire Nautilus Mini is a good starter tank. I keep one for my Cheap Menthol Blend. I spent about $100 in mistakes. Maybe more. Thanks.
