I may be a dissenter here but a GOOD powder-coater can give your bike a nice "paint" job for $100 or less - particularly since your bike doesn't need extensive prep. Plenty of custom steel builders use powder and when done properly powder can look as good as paint (metal flake being an exception) and will be more durable. If you go this route make sure that the powder-coater has lots of experience with bikes. As mentioned previously, round tubes, lugs, and the numerous threaded bits give the inexperienced guys a lot of room to f_ck up.
