It's hard to say. In the Portland Metro area frame & fork powder coat is from around $135 to $175. Some places will charge extra for sparkle clear coat over color or the like, and others won't. Liquid painting around here has a long wait & turn around time. PC is relatively cheap & durable.
I had my first R20 powder coated and I like it, although I don't care for the sparkle clear coat and wish I had chosen a different color.
