the local shop around my area is changing around 125-150 per frame in practically any color. it's really up to you, but i don't see the advantage to powdercoating a frame unless the frame was a reallly nice frame which had a crappy paint job =\
what i'm trying to say...is that it's not advantageous for me to powdercoat my huffy conversion lol
other options include:
1. painting via professional
2. painting via yourself (very cheap and can be VERY good if you follow some crucial steps)
3. cover it with hella stickers like those mash dudes lol
