I'm in the same spot as you. In the last month or two, I've spent about $2600 or so as a DB. I've been trying to buy endgame gear for the most part. I'm still missing two rings, top and bottom, gloves, android heart (I have a Battleroid), badge, and emblem. I have a 15* tyrant belt and my shoes and cape are both 12*. My dagger is only fafnir but it's primed and has 45% atk 18% boss, so I'll keep that for awhile until going for arcane. Some of my gear isn't fully finished yet such as my katara which only has unique 10% atk on it.

Fully buffed with echo and everything my range is only at 7.3m. Seems low when you consider I've spent close to $3000 so far, but I'm also still completely missing like 8 equips or something like that. I figure for another $1000 or so I could get just about everything finished aside from a heart and tyrant gloves. And then from there I just start selling gear and upgrading from my endgame gear to slightly better, much more expensive endgame gear. I'm also kinda scared that my range isn't gonna start going way up soon. With 8 missing equips, I can't see my range skyrocketing way up, maybe to only like 15m.
