Yeah I have a bunch of 6L's for the S90 & S95 too. I just purchased some knock-off 5L's on Amazon for $3 each. I bought two sets of 2, tried to cancel one because the shipping was listed as a 1.5 weeks, but they went out the door before I could cancel. None are here yet after a week, but they're all in the mail. So I'll be out about $15 for 4 batteries and a second charger with a AC and cigarette lighter connection. If you go this route, be sure to look at the milliamp hour capacities (and the user ratings).
