sound advice works with the custemer on price. i used to work there so i know how it works. plus they are one of the few shops i trust in town. all i was giving was an oppion, do what u want with it. i dont know if they do stuff on the side or not. thats none of my buisness. but i know they will do a great job and if there is any problem, or at least when i worked there, u could get in that day or the next.
