not got your exact model listed, but these are a good company to deal with. Ring em, and tell them the part number. Theyll tell you which one is right. Ive been using them for a good few years for laptop spares as they are just down the road from me.
Ive always found them hugely overpriced myself. Tried to charge me £115+vat for a DVD drive for an Acer laptop a couple of weeks ago - I just laughed...
Ive never had an issue, though I have been using them for years, and they are only a 20 min drive from my house.
