Drum vs Disc, Power vs non Power

Another thing to take into account, I'm having trouble locating 10" for my 69 Cuda. The better brands have dropped them (one bloke quoted $400 for each drum-Bendix). I can get 'no name' ones over here for about $280 a pair, which would be about the same cost as to get them from the states to here, but how good is the quality? disc might be the best in the long run.
Cheers,
Monaro.
