Rather a wide answer,i bought a Bob James kingfisher kingpin back in January for £172 plus £4 postage,an insight one(purple) went for £220 plus pp last week.If selling them on Ebay i would expect around £180 plus postage in the coarse season.Its now the close season so prices will probably be lower and then you have selling costs and paypal costs.If you want a more accurate estimate, search on Ebay for Kingpin reel, then click Advanced search, then click search. Completed listings of kingpin sales will come up with past prices.Be aware its an auction and anything can happen,unless you put a buy it now price or sell it on here.(you will probably have a few takers)
