buying/installing a dual layer dvd player...

right, so I'm on a laptop, HP Compaq Presario R3430 to be specific

and it came with a DVD+/- R/RW drive

I want to take that out and replace it with a Dual layer writer

are there an considerations I need to know of before buying one? like making sure it's compatible and such?

I was thinking about buying this one

and what are your thoughts on something like this:

also, what do I need to know about buying one for my Home PC? are they all compatible with all types of PCs?

do you guys think this is okay: http://www.newegg.com/Product/Produc...82E16827151066

personjally, i've always used plextor's in the PCs and also i have a Lacie d2 external for my mac...always worked for me

could you give me a link to a good inexpensive plextor you'd recommend? or any any of those decent? I'm not looking for the end-all be-all DL DVD burner, I just want something decent and inexpensive as I already have a good DVD burner on my laptop, it just isnt a dual layer one

i'm unsure of good models in those price ranges...maybe someone else knows more???

what do you think of this one?
