I recently bought an IRO Angus for similar reasons; sometimes I still kind of hit myself for not getting the Mark V and saving myself a few bucks in the process. Look at the IRO Mark V; can be equipped for single speed, fixed, or both.

The best deal is the warranty. If anything happens to the frame, you can get it replaced for half the cost of a new one [which is $125]. The frame is comfortable, durable, and fast.
