Don,
Moneys aside, I can send you a copy of the plans if you'd like. Send me a PM with your email address.
Unless you want to do some custom internal structural changes and slight planform modifications (like the UFO 25 developed in this thread for example

), scratching is just fine. Where a laser excels is at producing complex shape formers with various cutouts. Anything irregular is nice to have laser cut.
You should check out Ralph's (R_G) and Dave's (Rainedave) UFO builds here on the forum - both superb build threads.
I hope this helps.
David
