I paid less money for DiskWarrior than I did for Micromats' Techtool Pro, something like $69 vs $99. However when I contacted Alsoft a little while back telling them the new G5 with Nvidia 6800 couldn't read their disk (A now well known issue regarding OS X.3.4), they said no problem and put my name on a list for the new disk that will be readable by the NV40 equipped G5..
I contacted Micromat and said same, and they told me they would sell me a disk for nominal fee of $25 that will work!
Mind you, I only contacted Alsoft the one time 2 months ago, and yesterday via Fedex I get a new Original copy, disk with serial number in a very nice soft plastic disk case at my door...
There is just one word for Alsoft..... Class.
