Skream is not as well known in the US but is quite popular outside the states.

If you've never ridden fixed before, you might consider buying a bike that is drilled for at least a front brake until you can safely skid.

Some of the more "hipster" fixed gear brands include Leader, Constantine, Aventon, Skream.

Cinelli Pista is a well known fixed gear. The Dolan Pre Cursa is a very good aluminum track frame. Mash SF and Squid make nice fixed gears.

For cheap steel frames, there's State Bicycle Co and the Mercier Kilo. Pricier steel ($400+) includes Wabi Cycles, Surly Steamroller, and All City (Super Pro, Nature Boy, Thunderdome).

This is by no means a comprehensive list. Do you care what material the bike is (steel, aluminum, etc)? Are you looking for more road/street geometry or track? Maybe get an idea of exactly where you plan to ride your bike and what you're looking for.

For your first time bike, for a complete bike I might suggest the Mercier Kilo TT for $500USD. If you're just looking to buy a frame it gives you a lot more options but will be more expensive overall to do a custom build.
