For the Blu-ray player. As buwish stated find which models fit.
I swapped the DVD drive in a Tosibia A205 for a blu-ray drive. Was a PATA model and cost $100. Did a google sarch and found the lowest price - worked great.
Bougth a tosibia A305. Picked because they take same battery, and DVD drive was was easily replacable. My intent was to swap the blu-ray drive into the new laptop - WRONG. New laptop DVD drive was SATA. In looking for a new Blu-ray drive they wanted $200 for the the identical drive, but in SATA version. Rip-off as there is very little diffence in manuf cost between PATA and SATA interface.
Did some more goole search and found several places in ASIA (I was very leary), but found one in Tiawan that had good reviews. Ended up ordering it for $100, free shipping. They even sent it Airmail and I had it within a week.
You will have to factor in Customs and or VAT taxes, Which currently are Zero in the states.
