Beginner looking for a way in

Hello. I've recently been wanting to get into the fixed bike scene. I was originally planning on buying a Throne bike but after much research, found out that would not be a good investment. I would use the bike primarily to get to and from work(12 miles). I used to ride on a bike i bought from target but I feel like fixies go a lot faster since i find myself getting dusted by them, could just be a skill issue but they look fun nonetheless. I've seen most people recommend to build them from the frame up but it's something I'd really rather not do since I can't imagine I'd notice the difference on a pre built one as opposed to building my bike in a very intricate manner. TLDR, Whats a good bre built fixie on the market right now? Or if I were to buy a frame what all do I need to buy to finish the bike, which is the part that intimidates me the most since I have no prior knowledge with fixies. Budget is $800-900 and if I were to start from scratch the frame I have in mind Is a Tsunami SNM100

Thanks to all who take the time to read/respond.
