Los Angeles riders - where to shop?

[smurf]

I haven't touched a BMK bike in 15 years, but am looking to pick up a bike for some casual street riding and maybe some nostalgic freestyling. I'm having trouble finding a good bike shop in my area. Any LA riders out there know of a place in the Hollywood/Mid-Wilshire vicinity... or reasonably beyond? I'd like a decent $300-$400 bike for a 6'2" rider.

One dumb (forgive me) question: In looking online, a lot of bikes lack front brakes. My choices get limited in looking for a 20.75-21" TT frame. Is it easy to mount front brakes if I find a bike I like without them? I'm open to bike recommendations too... online purchase or otherwise.

Thanks.

you'd have to buy the parts, but it'd b easier to just
a) buy a bike with a fork with brake mounts
b) buy a fork with brake mounts to put on

besides you dont need front brakes for freestyle or street
