Nice...! I could give chapter and verse on the 1N's beauty and efficiency...
But, you're mad to ask for just $250! $500+ for that babe in good condition (speaking of which, you may want to post photos and description of it for other APUGers to gloss over).
Might that be 'cause you're not including the battery, LOL!
No, it's like this Sunshine, the world has gone M A D with digital. The 1N still commands a hefty second hand price and dumping it for $250 (or even the reductio absurdium of $150) is on an emotional par with shooting Bambi.
