Which DVD burner to buy for Laptop.?



I have a HP ZV500z laptop with a DVD/CDRW . I want to get a DVD burner for it and am not sure which slim DVD burner will fix, or which is better.

I see there is a Pioneer and a NEC ND6650. both are about the same cost 100$+/-

Any recomendations would be appreciated and which one might work or not.

I have heard that the bezel needs to be chnaged out, which is fine by me. I am not sure which brand is installed in my laptop
