This thread has been so informative and helpful due to everyone's inputs that it has changed my thinking completely. The email after yours is a person with machining experiences who vouches for 3D printer quality. So here's what my priorities look like today:
1. Try a 3D printing service online that produces parts not too much superior than what a home printer costing say $1000-1500 would. This would validate the quality 3D printers can produce (I hope). If parts look good for my "proof-of-concept" testing, then I'd buy a printer myself!
2. If this doesn't fly, then get the parts machined .... from individuals who own mills. Craigslist? This forum somewhere?!
3. Maybe a year down, I can restart my search to own a machine if it makes sense at that time!
Such help as this forum makes me wonder:
From my college days when we built 8085 systems and painfully connected to bulletin boards to just download some driver, to today's omnipresent, omniscient powerhouse of collective knowledge -- the Internet -- that solves nearly every problem! I would guess that we all are probably the luckiest generation ever to have lived or that will live on this planet to have seen warp-speed growth in the last 40 years and the coming perhaps 20 more!
Thank you to all.
