If it were my money, I'd probably buy an All-City Big Block. Maybe an All-City Thunderdome if I wanted to spend more money and have something more track-oriented. Not an All-City shill btw. Some of the other options at that price point are just kinda weak comparatively IMO:
Dolan TC1- single-sided dropout plates are a bummer
Surly Steamroller- probably doesn't translate as well as a track bike
Planet X Carbon- makes you look Fred as ****
What I did some time ago was buy a Felt TK2 on ebay. I like everything about it except for not having waterbottle mounts for road rides and the dumb lip around the dropouts that make it annoying to get a wrench on the track nuts.

edit- Soma Rush might be a good option too
