I've been trying to find the month/year(s) this TV was was sold and it's MSRP. My employer is selling this TV so I'd like to find out what it cost then, what it's worth now, etc. so that I can strike a deal. The person who purchased it for our office is long gone and I don't know if an receipt is available. I've been trying search via Google in general and eBay, but i'm not finding much. Thx!!
