I've worn Docker's slacks to work for years.  I can generally get a year or two out of a pair, which to me is quite reasonable.  They keep their shape and clean up with a minimum of fuss.  They've always been reasonably priced (especially if you avoid the malls) so I've always felt they provide value for money.

The only issue is sizing.  Docker's uses the concept of vanity sizing.  If you don't want to face the fact that you've, um, spread out a little, then these are the pants for you.  In general, waist size is actually 1.5" to 2" greater than nominal.  A so-called 34" waist is more like 35.5".  A 36" waist is really closer to 38".  As long as you bear this in mind when purchasing, these will be perfectly serviceable slacks.
