As far as Mods go, if you don't mind the size I would suggest that you have a look at the Wismec Reuleaux RX200. You can find them for around $40-$45. They are a 200 Watt 3-18650 battery Mod. For any regulated Mod I would recommend Samsung 18650 25R5s (~$5 ea.), get a set of them for the Mod and another set to have charged and ready to swap out. You should also pick up a 18650 4-bay charger (~$30). Another Mod I like is the Joyetech Cuboid 150 or 200 (2-18650s). Both Mods will cover you well for nearly any Temperature Control (TC) and Wattage Vaping as you go foreward. My tank preferences have advanced but you could go for an Aspire Nautilus (tighter draw, less air flow) for around $28. I like direct lung with easy unrestricted draw so I like FreeMax Starre Pro tank (they come with TC, Ni200, coils only so if you want straight wattage you will have to buy some Kanthal coils). Vapeston Magnus is also a good tank. I also have some Aspire Atlantis tanks as well.
