I'm a Luke owner, and you will have to pry it from my cold dead hands to get me to give it up! For a player with smaller hands like myself, the neck is nirvana. My buddy has hands that are quite larger than mine, and he loves the Luke too. (He plays an Ibanez JS-100 most of the time.) I'm not crazy about the EMG-85 in the bridge, not enough power for my tastes, but the singles are great for clean stuff. (One of these days I'm going to drop an EMG-81 in the bridge and see if that helps things out.)
All in all it's a fantastic guitar, but the neck is quite radical, so your friend might want to try one before he buys. Except for my old '78 Ibanez Musician, I've never come across a guitar neck like the Luke's.
