Amazon has the Canon G10 for the lowest price yet at $464 with free shipping (link below). This is the lowest price I've seen yet for the G10.

If you've been waiting for the lowest price on an LX3 without going the Microsoft/Ebay cashback route, this may be the ticket. J&R has them in stock and is selling for $399.99 with free shipping.

Update: Sixth Ave has them for $398.54, but I've not dealt with them. I have bought from J&R with good results. Both Sixth Ave and J&R can be accessed via the link above.
