do your own work and you'll spend half the money.
if you dont drive anything exotic, theres no reason what you need installed cant be done on your own or with the help of others. theres a handful of members that live on LI here that im sure will be willing to help you out a bit if you really need it and maybe throw 'em a few bux/buy 'em lunch.
id be glad to help you out, but im upstate at college right now. i have a blast installing stuff, so if you ever catch me when im on the island, id be glad to help you out.
i honeslty hate having my setup basically all done. im projectless right now and sooo bored.
