this is a steal i bought one less then 6 months ago for 200odd after looking around everywhere 78% is a bit far they usually fetch around the $200 mark if you look around. fine shipping might be high but its still 20-30% cheaper then anywhere else and still half the price of local dealers
dont forget the $10 off shipping voucher
