A really, really fantastic fruit flavor is Liberty Vapor's raspberry lemonade. Maybe lemonade types aren't really what you're into, but if you're looking for a really effing delicious, spot-on fruit flavor, that's it. I think their prices are $5/5mL, $8/10mL, and $18/30mL. Not bad at all for some really amazingly-made liquids.
Sidenote: Their Strawberry Cheesecake is just about my favorite liquid of all time, but I'd consider that more of a dessert vape than a fruity one.
On the "premium" side of things (cough, quotations because in 9 out of 10 cases (Five Pawns being the only arguable exception) you can find just as good (if not better) liquids for a much more reasonable price. (Just keep in mind that no matter what, liquids should have responsibly-sourced ingredients.)), I've heard really spectacular things about "Lushington" by Stash, if you're into the idea of an amazing roadside peach flavor. Pretty sure it's a high VG dripping liquid though, so keep that in mind.
(Apologies for the long tangent in the middle of that sentence there.)
