Yes that WAS a sick board. Now its 8 years old and probably not worth more than 100 bucks probably closer to 50. There just not much market for old boards; I can buy a 2 year old model like new for 150 or last years brand new for 250.
Also board length is more dependant on your wieght than height. So if you tell us that; we can recomend board lengths.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
