as the captain said £120-£150 for good condition, little bit more if mint
if buying then make sure the spokes are the correct 12g ones and are in good condition as they are hard to find in large quantities (over 20) and you will pay around £15 for just 10 12g spokes and nipples if u can find em
oh and also make sure the axles are ok as they can strip out easily and ive never seen replacements for sale!!!
