I got the new Pioneer 108 & its really good, bought some 8x Datawrite grey dvds for it & they have all played perfectly (DVD/Console/Data) also theres region free firmware out for it so you dont have to worry about what region the DVDs you backup are from, havent used the dual layer disks yet but I know the Pioneer burns them at 4X so if thats important for you check on the other 2 drives Myk recommended (both of which have great reviews) as a lot of dual layers only do the D-L at 2.4X.
Only low point with it is the cd burning speed which they only put at 32X for some reason but its no big deal as Im phasing out cdr anyway.
