I own zzzs.org, which i think is a better name, as it has much larger number of google results in comparison to lkkk, it also has some wordtracker, and meaning as well but still i don't think its worth more then just above reg fee for resellers. Hence, your name is also worth reg fee or just above reg fee for resellers imo. Though it is definitely worth keeping a year or two, its value will surely increase imo.
