I usually get flavours apprentice from perfect vape, if you have better makers to try let me know
I assume since you said "flavours" that you're from Europe and not the US? Also, you'd like to know other
makers to try (ie. flavoring manufacturers/brands,
not vendors/websites who sell them in the US)? If those things are correct...
In addition to using TFA flavorings (which many who DIY also use), you might want to try some of the Capella flavorings, too. IMO, 2 that are very good are their Sweet Strawberry and also their Blueberry Jam. Lots of people like their Vanilla Custard and their Marshmallow, too. Many of One Stop DIY Shop's "One Stop Flavors" and "One Stop Blends" are liked by quite a few of us on the ECF. They're manufacturered here in the US, but the most popular ones are also sold in Europe...on Chef's Flavours website and another 1 that I can't think of right away. They're already formulated and/or blended flavorings that are
ready to use singly...in your own PG, VG, and nic base. Recommended % to use them at is 5% if you're a high wattage vaper and 10% if you're a low wattage vaper.
I'm sure others will come along, that will have suggestions of some of their favorite flavorings from other manufacturers, too. Most everyone who DIYs has some favorites in more than 1 brand.
