I don't want a collection of bussekin. I want users--select the right one for the job at hand. If it doesn't fit a need, dump it.
I'm thinking of thinning out my collection for that very reason. I've got a DDF that's never been used, a SOD and a Dumpster Mutt that have never been used, and I hate to have that money just sitting there if I'm not using it. I like collecting things, but my tastes are changing a little.
