i wouldn't spend more than $100 plus tax on a single-stage powdercoat job. Even doing a clear or a metallic, and you should still come in under $150. That being said, Bianchigirl still gives good advice, as the paint looks good in that pic.
Don't let anyone heckle you for your electro-forged schwinn. Yes, they're heavy and common, but the prices keep going up on them, and they're very durable. A nice bike, made in the USA, easily serviced components, matched fenders...I like it. And the value of old bikes in terms of money changes a lot from year to year. The value of old bikes in terms of preferences are variable from rider to rider.
