i have a sony cd-rw which i am pleased with performance wise but its sounds crap and cheap, also an lg cd-rw which is quite & smooth in operation but features are just not there, also a pioneer dvd, 2nd one i have owned and its crap noisy and unreliable as was the first, i would never buy pioneer again, i think i will go for teac or plextor next, but my friend just bought a plexwriter and it to is crap not like my other mates one which is very nice.
