$0.60 per disc ($30.00 for 50 discs), is an excellent value for quality media. As for firmware, Liggy’s Beta versions are mainly for burning a larger variety of media at higher than official speeds. Read HERE.
You should read through some of the threads, and DO NOT RUSH! Take time to absorb the info, and yes there is quite a bit! DO NOT expect to understand everything over night! If you do, you will be VERY dissapointed. I know because my head is still spinning! :o
Edit: with liggy’s Beta 8
TY 8x -R media (MID TYG02) will only overspeed to 12x.
TY 8x +R media (T02) can be burned at 16x.
IMO, 16x isn’t worth the risk (of a poor burn), unless you do alot of testing with consistant results.
