HP 27 - Rare These Days?

[Old-HPGuy]

Hi - have looked through materials on this site and others regarding the rarity of various HP LED type calculators. I have an worker friend that's willing to sell a good, working condition HP 27 with original case, user manual, good working battery (rebuilt), etc.

The asking price is $250 and from what I've seen the HP 27s are rare these days. I've not followed this market but did use HP calculators back in my days as a young engineer - so I know they are well made.

Any input or advice about the asking price?

Thx.
