is $150 for an 8000 BTU air conditioner a fair/good price?

[vexingv]

i'm gonna need an AC in my apartment with summer coming up, so my bro has a friend who's moving and selling his AC. the AC is one year old and i think its a LG (or maybe GE) 8000 btu unit. the guy wants 150 for it...is this a fair/good price; i have no clue about anything about ACs....

5000's go for $100 so thats a fair price, little high IMHO.
