Hi
@Ladybug24. Tanks can last a really long time. When you get into the better tanks (glass) all you do is replace the coil and wash the tank occasionally.
I would recommend getting an iStick 30W (
EleafUS Products - Mt Baker Vapor - Electronic Cigarettes $35) mod (battery) and an Aspire Nautilus Mini(
Aspire Products - Mt Baker Vapor - Electronic Cigarettes - $25). Vape really starts to shine with flavor when you can dial in the wattage (power). Both the iStick and Nautilus mini are user friendly and top quality. 10% off coupon at COUPONS -

Your current tank with a 510 to eGo adapter ($4) would work on the iStick 30W, as would the recommended tank by the above poster.
There should be some sales for the 4th of July found here : DEALS and STEALS -

The 30W is in pink. It is a 2200 mah battery.
If you do decide to invest in better equipment, make certain you get at least a 30W battery, as it allows room to grow without having to buy another battery for the next level of vape (sub ohms).
My journey, Nautilus on vision spinner 2 clone in center and on iStick 50W on right.
Good luck in your journey.
