Help finding a gravel frame

[pushpush]

I'm looking for a gravel frame. I'm hoping someone can help me identify some candidates. I've scoured the existing threads but don't see anything that seems like a match.

Geo similar to a stigmata. More fast, less adventure, but still quite capable.
Internal routing
BSA BB
Aero shaped tubes would be nice but not required
Internal storage is a plus but not required
I don't care about seatpost shape. Aero is fine. Round is fine.

Any ideas?

Carbonda 707 is generally the best gravel option currently available in this part of the market IMO. Just ordered one myself.

Thank you. I'll have a look.

For a great cost effective, more traditional and lightweight frame, I like the Seraph GR029.  I purchased mine in 2019, and have been riding it for 4 years now.  I have over 7000 miles on this bike and it has served me well.    (I have ridden the crap out of it and have had no problems with this build.)

By today's standards, it only fits a 42 wide tire but this has worked out well for me using it on many gravel grinders.     
My 56 clocked in just over 1000 grams and it has a lighter weight fork.    (One would think that most Chinese gravel frame manufacturers would be offering more under 1kg frames, but it appears to me they are producing heavier frames these days than in the past.)
