You can get a fully customized and built fixie for less than 10k at AA Fixed Gear. They also sell parts and accessories for fixies.
There was a time that I was really into biking and I wanted a fixie because it looked pretty cool. They were bikes that only some people knew how to ride and looked very minimalist because of it being stripped down of all the "unnecessary" parts. I was talking to a friend who rides fixed gear and swears by it. He had a really nice looking bike so I asked him where I could get a fixie for cheap. I didn't want to spend too much because a fixie doesn't have a lot of components so it should really cost less than a bike with gears and all that other stuff.
AA Fixed Gear imports their stuff from Taiwan. You can choose the color for every part that you put so you can make it as plain as you want or in all the colors you could imagine. After choosing the color of each part of your bike, they will assemble it for you in a few hours for you to take it home.
For those that want to get into riding fixed gear, please put some brakes on your bike and practice riding until you get it perfect in an empty open lot. Please also read up about riding fixed gear before you get into it. If you don't know how to ride fixed gear, the bike can be the one to control you and you can get seriously injured. Remember to ride safely and responsibly! read more
