I built a few 1/700 scale ships about 30 years ago. Waaay before photo etch. They were bad enough then before I needed glasses, had hand tremmors, lower attention span, back surgery, and a weak bladder - I'm more of a 1/32 scale guy now - just doing this teeeny 1/350 for a friend. Normally I don't decend much below 1/48 scale.
Kudos to those who can do the small stuff though!
Cheers,
Paul
