I have been an avid fan of Lite On hardware for many years. I have purchased 3 LDW-411s in the last year (myself, wife, brother). However, I just got the NEC 2500A and I have been very impressed with it so far. Does this mean that I am no longer a fan of Lite On? Absolutely not!! I just feel that at this point in time, the 2500A is a better option than the 811s.
