Cheap motherboards for Toshiba Satellite L505D-S5983

[Moosha]

Hi, I need to replace my motherboard. its part number is v000185540. Any suggestions? The computer it is in is not worth a lot, but I really liked it.
Thanks

The cheapest I can find a motherboard for that laptop is $155 (used), so it's REALLY not worth it. The laptop itself (in a working condition) is barely worth that.
