I can't say I have a lot of experience with other tools.  I thought using my 
scanner was subpar and the DTP20 is a huge improvement upon that.  However, I 
haven't actually scanned a target (I guess spotread should work to read a 
target of known values) to get an idea of where it's at in terms of 
calibration.  My batteries run out very quickly too, I usually use it plugged 
in with external AC-power.
