I would say if its a current model and in good condition then you should be getting 50-60% of the new cost older models = less demand = less value say 35% maybe a bit less, as for your stuff it looks current now if its say only a season old and well looked after then no less than 50%, try and sell local if you can, ebay can be a gamble especially if you start at .99c. try here first and try and stay firm with your price if you are confident that the gear is in good condition.
goodluck
