Does anyone on here use one of this things?

I guess Lyman and RCBS both make one
as well as other brands...I have been looking
and dreaming about one,but not sure it is woth
the extra cash..I want one that you can
change the powder with ease as well...Right
now all I use is the Lee dippers and my fingers
as a powder trickler....So if you have one,what
brand and how do you like it? Thanks
