Beginners are always looking for the next deal and most cannot tell what is a deal and what isn't. If you buy it on your own you may very well end up with unusable paper weights. Can you take someone experienced with you to look these over? I certainly would not let anyone disassemble anything I had for sale so I think you might count that one out. Has he tried to get rid of this stuff to others? If so why haven't the experienced modelers snapped this bargoon up. I always caution beginners buying used stuff to be extremely cautious.
