FYI diy folks - outcome of the laser transplant out of the aforementioned Apex dvd player to the 303/300 is it plays fine but the drawer mechanism snags somewhere & hangs up leaving the drawer ajar about 1". The drawer can be closed w/a slight nudge but it isn't perfect. The drawers are almost identical but must not be readily interchangeable w/each other. The laser drive seems to be a little noisier than the original too. There were slight different physical differences which appeared to be cosmetic between units. The laser drive out of the Apex was dated 2001 which was probably 5 years older than my 303/300. But bottom line it works if you can live w/the drawer hanging up. I'll probably wind up ordering the exact replacement from Cary & swapping it out now that I have practice.
