from what I have found out, most are much of a muchness, they excel at certain things, brand loyalty comes into it, too, its better to burn at lo speeds for some stuff, in which case any drive probably would do.
I used to worry about getting the right thing, now its not too important as long as it does what I want it too, I am not getting hung up on it, there is no best per se.
buy what you like its as simple as that.
why not find a 215, they are still going if you are that worried about the 216, I don't think its worth worrying about too much, unless its really serious.
new liteones supposed to be good, lg is,
pioneer has the best build quality by far, which would sway me, heavier, bigger, better inside, too, yes I have looked, but doesn't guarantee best burns or even reliability of chips or lasers, oddly enuff.
