for me my first pv is lavatube -> gg with kick with ody -> provari with zap.
try to get your most comfortable combo be it price or mods and carrying at ease.
fyi the different combination will give you different taste of your juice.
If you wanna try vv at a cheaper price you could try zmax.
try to get a cheaper repairable like nova play around with it.
Don't waste time on carto and LT its a waste of time and money.
Go do some research before you buy
like GOOGLE and Youtube.
hope this helps
