well DHP isnt around anymore... but i would suggest finding a local guy. there are many of us out there and we do know what we are doing. i'd say talk to them first. see what they have done and how long they have been tuning.
i heard rumors floating around of people offering free tuning to people to be used a guinea pigs! so be careful too. heck if you make friends with them you may end up with free tuning for as long as you know them! i have a few friends that got more tuning then i did lol... well almost more tuning.
