I received way too many scion requests off Mason31’s post so I guess I should offer these. I have a vast collection of pitanga (eugenia uniflora) because I adore the fruit and have ended up with some winners.
Seeds: $3 min 5 - Vermillion or Black Star, don't have others right now
Scion: $5 each, see below for size, I may be able to spare larger diameter but unlikely
Regina (seedling) really large red fruit, they go darker than most reds but I'm going to call it a red.

"Dark Purple" this was from another collector and said to be ultra sweet, he was not kidding, it is cloyingly sweet.

Black Star Pitanga (this is a seedling, but fruit goes dead black and is the best flavor. It is also has large fruit)

Black Star, super productive, sets super well

Vermillion (grafted) fruit has a great flavor, and pumps out fruit, it is basically flowering and fruiting non-stop I see why this was selected

Misiones "giant" Pitanga from Marcos in Argentina, the fruit was very small and totally smooth so I guess a black dasyblasta. It was a first fruiting though, so it will probably get bigger. Flavor was VERY sweet. I did get one large fruit off it recently, randomly. Unknown. It is definitely more cold hardy than the others I have.

Shalom's Giant Red (seedling) supposedly giant fruit, got the plant mature from another collector, it has not fruited for me but he is a legit source and I trust him it was giant

This is the size of scion I have, mostly

A nice handful of fruit from the Vermillion (red), and some Black Star at the bottom
