I DIY, but i do single flavors, cola, cucumber, pizza, red licoriceYah, my only issue is the cost to start.
I want to make recipes like
strawberry shortcake
Blueberry cheesecake
Orange sherbet
But I know it's a trial and error. So, it looks like $100 is a good "start up" cost...
other than that There are a couple flavors I buy from ePipe mods
and a few NET tobaccos pre-made juices & flavorings from My Vape juice
