What Rob (pickle) said. It's value depends on what someone is prepared to pay. Raleigh burners aren't the best bmx's out there, but they were popular and therefore lots of people feel a connection with them. Other brands such as Peugeot or Falcon Pro weren't as popular, so their appeal isn't as widespread. For example, i bought a complete burner last year for £175. The year before i bought a complete Falcon Pro for £115, and a few years ago bought a Peugeot Black Lion bmx for £31 (it was a wreck though). All were auctions on ebay. Like i say, it depends who is looking for one at the time, and how badly they want it. It only needs 2 people who are after the same thing for the price to rocket. I'd say about £100-£150 is about right as a rough estimate
