Mission 727 value?

[KrautNotRice]

Found some 70s Mission 727 in nice shape. I wonder what they're worth?
Seems like Missions are more popular in Canadia than the States. I'd possibly make an offer on them, but don't wanna overpay or insult anyone.
Any help is appreciated!
Best regards.

PS: This is what they look like (grabbed pic off internet):

They are nice speakers and sound good, but low on the radar for some funny reason. Around here, expect to get between $100-150.
