I have a Premium, and although it has more features than my old and worn out 2410, the 2410 was much, much better imho than the premium - which almost cost 3 times the price of a DL NEC burner (about Â£80 if memory serves for the pemium a while back, and you can get an nec for less than Â£40 now).
Someone else also added to an earlier post of mine, it may have been a mod, can't remember, that they too was dissapointed in the premium - also agreeing the older 2410 was a classic and better.
One annoying habbit of my premium is that after writing a cdr, often it will start a scan at a slow speed and go up to a reasonably fast pace - I can sometimes fool it by refreshing from explorer, but not always - and there is a click from the drive like it's adjusted itself for some reason to go slow, or fast again. I cannot see a setting for this in Plextools config. The Premium is not a bad drive, but if I could have bought a 2410 rather than the premium - I would have gone for that.
With prices for DL dvdr burners so low now, if anyone was going to invest in a new burner, I would certainly recommend checking out a great dvdr/cdr burner combined (from reviews). Admittedly I have not checked current prices, but it seems it is just not worth buying a cdr burner when some dvdr/cdr drives can do a very good job of both these days.
