When i have put CDRW and DVD Roms in people's machines I have used them and they are great especially as they are cheap. A little dickie bird told me that Liteon is actually a JVC make? Maybe why they are so good.
as £84.99 at Dabs. It's a retail package too. Does all the formats except DVD RAM, which I hear is on the route of the Dodo anyway. Can't say I know anything about Liteon/JVC, but this has bagged a good 4.5/5 from 25 reviews on Ebuyer.
No worries - the way prices are falling I'm betting the 4x will be around the £60 after Christmas as more 8x come on the market. The new Plextor 8x has only been out 7 weeks and it's already dropped from £195 to £149.
