Good for you on trying to quit smoking. If there are any vape shops in your area, you might want to stop by and look over the various devices they carry. Since you are just beginning, I'd suggest sticking with regulated devices for now. They are safer and easier to use.
Just remember that prices will be higher in a shop than online for the same device, but shouldn't be outrageously higher. Shops have overhead like employment expenses, etc.
Find something you like at the shop, then do a little research on it. If you still feel good about it, then go ahead and pull the trigger.
