Regarding the members here being cheap-skates comment makes me wonder if that is a psychological factor of forums such as this one. There is a marque specific car forum that i subscribe to that seems to agree that people who own the things are also frugal. Perhaps it is not the owners as a group, but the ones who frequent the forums as a group? In other words, the true fanatics of the product as opposed to the ones with a month's supply of underwear?
Anyway, Dr.Fish, go for them, I would. Use whatever strategy you feel comfortable with, and yes, these will probably go for around 3g's+/-.
