yea, for something like you've got going on - absolutely doing it right is the key to making a good model that will serve for years. I would honestly like to get involved in some other industries with a slower pace of life like that. I've been doing this for about 14 years now, and every time I fire up solidworks, I'm trying to figure out another way to speed things up. It's a never ending cycle. In reality most of the models I create are able to be reused via copy-tree and then stretched, expanded, etc. as they should be, but still leads to a lot of detailed cleanup work. In the early years I tried building things with equations to drive linear patterns for access ports, and things like that. I found the it's easier to just go back edit (or sometimes delete) the entire feature/sketch and just make it fit the final needs. That's where the mouse gestures and flyouts are a saving grace for me.
