On another note, I guess I never knew "lowball" had anything to do with anatomy. <<

And that's because it doesn't!

question, there is an add for mcintosh mc501 - recently they go for about 2,800~3,000 on audiogon...
the add: "McIntosh MC501's 1 year, mint, original box & manual from dealer, 40% discount! $6,600"
if i would offer 2,800 - is it considered "low ball" ?

No,I just call that offer BIG BALLS.

Go ahead, make your offer. Please report back to us. I would be curious to know how it works out for you.
