Check out page 194 in PCA August 2006 Issue 133. The drive you refer to is 73pounds. It is the first 18x speed drive but to be honest do you really need that extra speed in a drive for home use? To be honest I would look to something cheaper. That way if it goes belly up in a years or twos time it was more price to use viable than a drive 2 times the expense of a drive 2x the price doing the same thing. Personally never used it but just pointing out something to consider.
