You beat me to it.

Fact is, I'm finding CAD to be slowing me up but, I suspect that's because of the learning curve. Still, sometimes it's faster to rough out a thought on paper than it is to determine how to tell the d*mn PC what I'm thinking. So much faster that the thought can get lost while convertng to CADspeak.[:@]

As for scratchbuilding being cheaper, I don't see how. I've never managed, although I try to convince my wife that bulk materials buying is cheaper, I never finish that sentence ; "...cheaper than not buying in bulk".
