I'm pretty sure we can all agree that a $1000+ pen is expensive.

But what is the lower bound of an "expensive" pen for you now?

I remember when I bought my first Pilot Varsity, I couldn't imagine paying $25 for a pen. I thought it was crazy.

I'm still the King of Cheapies. I've held and written with a quite a few high-priced pens, some of which are amazing, but it still thrills me to get a sub $25 pen that, maybe with a few tweaks, writes as well as one 10x or 20x the cost. And, of course, it can also depend a lot on one's disposable income.

That said, I have some holy grail pens. And I understand--even when I don't share--other qualities of pens that justify their price to the person who wants them.

But I'm still curious: what is your definition of an expensive pen? What's the lowest figure--assuming a working instrument--you stop and think "really? Should I?"
