Need replacement mobo for VGN-S580P

Does anyone know of a place that has new or used motherboards for a Sony VAIO VGN-S580P for a reasonable price? So far lowest I have found is 425 bucks, still a bit steep for a laptop of 2+ years old.

BTW..I had my laptop sent in to Pell Technology for repair...what a nightmare these people. Strung me long for weeks and weeks on end saying that "the technician is still working on it". After a few months I had enough of it and told them to ship it back...then they finally came back with "it is beyond repair". A UPS label was created and charged to my card that same day...but it took another 4 weeks before they shipped it!

 

I think ebay is the best place to look as sony can charge in excess of $1000

425 seems pretty reasonable:\

 

More about " Pell Technology"
They kept my laptop for 3-4 months and asked me to pay $495 for motherboard replacement (they say), after one more month when I asked if they repaired it they said they don't have the parts, I waited about 2 more weeks and they send the laptop back, (NOT fixed).
Now they will not send me the money back, it is over 2 months since I made this payment, they keep saying that they will refund but they don't do it
10 days ago someone finally answered the phone and asked for the full card number and invoice number and said I will see the refund in few days... they lied again.
As far as I am concerned this is fraud.

 

if its costs that much...just take the harddrive out and get the files you need. buy a new laptop paying 400+ for ONE part plus installation fees plus hassels is not worth it. pay 300 more and get a new laptop like the NR or CR or spend a couple more hundred and grab an FW or an SR.
