i have a chance to buy a 5.1 interlude set. it includes 2-il60's, 2-il10's, 1-il36c, and 1-il120s subwoofer for 1500$. the owner travels alot so i dont think they have many hours on them, and he lives in a condo so maybe they havent been pushed too hard. i cant find any for sale right now and i have no idea what they originally went for. is this a good price or should i pass on them?
