You can get an idea of what it would cost you for paint and decals by one of the top shops here:

You'll need to download the pdf order form.

I gave up the idea of having my PX10 repainted after studying that form. I still may send the frame to them for touch ups. They could probably touch yours up and repaint just that top tube for you.

You can ship a frame by FEDEX for less than $20.
