Hi Angler,
I am also an engineer turned woodworker, hanging around here getting the info, courage and plans together for a workshop CNC. There is, I believe, a sweet spot for a self build solution for woodworkers at a reasonable costs (my target £2k-£2.5k) if the right balance of size, components and design are selected. Close but not there yet. Will be interested to see what route you want to take through.....it always amazes me how different people's 'must have' lists are.
